The weak persistent tracking the OffscreenReleaseHolderMonitor was tied
to the texture object, but the release() closure holds a raw pointer to
the monitor via its v8::External data. If JS retained texture.release
while dropping the texture itself, the monitor would be freed on GC and
a later release() call would crash.
Track the release function instead of the texture object. Since the
texture holds release as a property, this keeps the monitor alive as
long as either is reachable.

gfx::PNGCodec::Decode() returns a null SkBitmap when it fails to decode
the clipboard contents as a PNG. Passing that null bitmap to
gfx::Image::CreateFrom1xBitmap() triggers a crash.
Return an empty gfx::Image instead, matching the existing null-check
pattern in skia_util.cc.

* chore: cherry-pick fbfb27470bf6 from chromium
* chore: update patches
* chore: cherry-pick bf6dd974238b from angle (#50437)
* fix: remove duplicate MaxGeometryUniformBlocks from angle cherry-pick patch
The angle cherry-pick added MaxGeometryUniformBlocks in new locations,
but it already existed in the EXT_geometry_shader section on 40-x-y,
causing a duplicate struct member build error in ShaderLang.h.
Re-exported the patch from the angle repo to correctly generate context
lines instead of additions for fields that already exist in the base.

* fix: guard validatePerStageMaxUniformBlocks with ANGLE_SH_VERSION check
The angle cherry-pick patch that adds this field to ShCompileOptions
may not be applied in CI due to the angle repo not being found during
patch application. Guard the usage with a version check so compilation
succeeds regardless of angle patch application order.

* Revert "fix: guard validatePerStageMaxUniformBlocks with ANGLE_SH_VERSION check"
This reverts commit 9ebf565988.
* fix: add angle to patches config and re-export angle patches for M144
The angle entry was missing from patches/config.json on 40-x-y, which
meant angle patches were never applied during gclient sync or CI builds.
This caused the chromium cherry-pick to fail with "no member named
'validatePerStageMaxUniformBlocks' in 'ShCompileOptions'".
Also re-exports the angle patches against the M144 base, resolving
conflicts from the M142-targeted patches.

Previously the renderer checked a process-wide command-line switch to
decide whether to create a Node.js environment for dedicated workers.
When a renderer process hosted multiple WebContents with different
nodeIntegrationInWorker values (e.g. via window.open with overridden
webPreferences in setWindowOpenHandler), all workers in the process
used whichever value the first WebContents set on the command line.
Instead, plumb the flag through blink's WorkerSettings at worker
creation time, copying it from the initiating frame's WebPreferences.
The check on the worker thread then reads the per-worker value. Nested
workers inherit the flag from their parent worker via
WorkerSettings::Copy.
The --node-integration-in-worker command-line switch is removed as it
is no longer consumed.

* fix: correct utility process exit code on Windows
On Windows, process exit codes are 32-bit unsigned integers (DWORD).
When passed from Chromium to Electron as a signed int and then
implicitly converted to uint64_t, values with the high bit set
(e.g., NTSTATUS codes) undergo sign extension, producing incorrect
values.
Cast the exit code to uint32_t before widening to uint64_t to
prevent sign extension and preserve the original Windows exit code.

Chromium added a top-level package.json in CL:7485999 that sets
the type to module and breaks commonjs tests run via
node-spec-runner.js. This commit temporarily changes the type to
commonjs while running the tests, then changes it back to module when done.

Upstream DevTools' HostRuntime checks `IS_NODE` before `IS_BROWSER` when
selecting the platform runtime. In Electron, `process` is available in
renderer processes, so `IS_NODE` evaluates to `true` in the DevTools
context. This causes DevTools to dynamically import the Node.js platform
runtime, which uses `node:worker_threads`. DevTools Web Workers running
under the `devtools://` protocol cannot load Node.js built-in modules,
so the import fails and breaks features like the formatter worker.
Fix by swapping the check order to prefer `IS_BROWSER` when both are
true. This is safe because in pure Node.js environments (the only case
where the node runtime is needed), `window` and `self` are both
undefined, so `IS_BROWSER` is always `false` regardless of check order.

* fix: preserve staged update dir when pruning orphaned update dirs on macOS
The previous squirrel.mac patch cleaned up all staged update directories
before starting a new download. This kept disk usage bounded but broke
quitAndInstall() if called while a subsequent checkForUpdates() was in
flight — the already-staged bundle would be deleted out from under it.
This reworks the patch to read ShipItState.plist and preserve the
directory it references, deleting only truly orphaned update.XXXXXXX
directories. Disk footprint stays bounded (at most 2 dirs: staged +
in-progress) and quitAndInstall() remains safe mid-check.
Also adds test coverage for the quitAndInstall/checkForUpdates race and
a triple-stack scenario where 3 updates arrive without a restart.

* fix: prevent traffic light buttons flashing on deminiaturize
When a window with a custom `trafficLightPosition` is minimized and
restored, macOS re-layouts the title bar container during the
deminiaturize animation, causing the traffic light buttons to briefly
appear at their default position before being repositioned.
Fix this by hiding the buttons container in `windowWillMiniaturize` and
restoring them (with a redraw to the correct position) in
`windowDidDeminiaturize`.

- POSIX: validate StringToSizeT result and token count when splitting
the socket message into argv and additionalData; previously a
malformed message could produce incorrect slicing.
- Windows: base64-encode additionalData before embedding in the
null-delimited wchar_t buffer. The prior reinterpret_cast approach
dropped everything after the first aligned 0x0000 in the serialized
payload, so complex objects could arrive truncated.

fix: validate protocol scheme names in setAsDefaultProtocolClient
On Windows, `app.setAsDefaultProtocolClient(protocol)` directly
concatenates the protocol string into the registry key path with no
validation. A protocol name containing `\` could write to an arbitrary
subkey under `HKCU\Software\Classes\`, potentially hijacking existing
protocol handlers.
To fix this, add `Browser::IsValidProtocolScheme()` which validates that a protocol
name conforms to the RFC 3986 scheme grammar:
scheme = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )
This rejects backslashes, forward slashes, whitespace, and any other
characters not permitted in URI schemes.

* fix: use requesting frame origin instead of top-level URL for permissions
`WebContentsPermissionHelper::RequestPermission` passes
`web_contents_->GetLastCommittedURL()` as the origin to the permission
manager instead of the actual requesting frame's origin. This enables
origin confusion when granting permissions to embedded third-party iframes,
since app permission handlers see the top-level origin instead of the
iframe's. The same pattern exists in the HID, USB, and Serial device
choosers, where grants are keyed to the primary main frame's origin rather
than the requesting frame's.
Fix this by using `requesting_frame->GetLastCommittedOrigin()` in all
affected code paths, renaming `details.requestingUrl` to
`details.requestingOrigin`, and populating it with the serialized
origin only.

* chore: keep requestingUrl name in permission handler details
The previous commit changed the details.requestingUrl field to
details.requestingOrigin in permission request/check handlers. That
field was already populated from the requesting frame's RFH, so the
rename was unnecessary and would break apps that read the existing
property. Revert to requestingUrl to preserve the existing API shape.
The functional changes to use the requesting frame in
WebContentsPermissionHelper and the HID/USB/Serial choosers remain.

The sender-mismatch check in invokeInWebContents and invokeInWebFrameMain
used a negative condition (`type === 'frame' && sender !== expected`),
which only rejected mismatched frame senders and accepted anything else.
Invert to a positive check so only the exact expected frame can resolve
the reply — matches the guard style used elsewhere in lib/browser/.

git format-patch honors diff.renames, which defaults to 'true' (rename
detection only). If a user has diff.renames=copies configured at the
system or global level, exported patches may encode new files as copies
of similar existing files, causing spurious diffs against patches
exported on other machines. Pin diff.renames=true to match git's
default.

PowerMonitor registered OS-level callbacks (HWND UserData and
WTS/suspend notifications on Windows, shutdown handler and lock-screen
observer on macOS) but never cleaned them up in its destructor. The JS
layer also only held the native object in a closure-local variable,
allowing GC to reclaim it while those registrations still referenced
freed memory.
Retain the native PowerMonitor at module level in power-monitor.ts so
it cannot be garbage-collected. Add DestroyPlatformSpecificMonitors()
to properly tear down OS registrations on destruction: on Windows,
unregister WTS and suspend notifications, clear GWLP_USERDATA, and
destroy the HWND; on macOS, remove the emitter from the global
MacLockMonitor and reset the Browser shutdown handler.

Previously, GetProtocolLaunchPath and FormatCommandLineString in
browser_win.cc used naive quoting which could break when paths or
arguments contained backslashes, spaces, or embedded quotes.
Fix by extracting the CommandLineToArgvW-compatible quoting logic from
relauncher_win.cc into a shared utility and use it in both browser_win.cc
and relauncher_win.cc to properly quote the exe path and each argument
individually.

Previously, when trashItemAtURL: failed (e.g. on network shares or
under app translocation), the code fell back to constructing an
AppleScript that interpolated the bundle path directly into a string
literal via %@ with no escaping. This was fragile and unnecessary —
trashItemAtURL: has been the standard API since 10.8 and covers the
relevant cases. The fix simply removes the AppleScript fallback
entirely, so Trash() now returns the result of trashItemAtURL: directly.

Previously, UsbChooserController::OnDeviceChosen looked up the chosen
device_id via chooser_context_->GetDeviceInfo(), which searches all
known USB devices on the system rather than the filtered list shown to
the select-usb-device handler. This meant a device excluded by the
renderer's filters or exclusion_filters could still be granted
permission if the handler returned its GUID.
