build: remove macos hittest workaround patch

CL:6574464 changed BridgedContentView::hitTest: to use GetHitTestResult(), which
returns kRootView for any non-null, non-NativeViewHost view — causing
BridgedContentView to absorb all web content mouse events. In BrowserWindow,
content_view_ sits in front of the sibling WebContentsView and covers the full
client area, so it was always found first, breaking all loadURL page interaction.

Fix this by installing a ContentViewTargeterDelegate on content_view_ in
NativeWindowMac::SetContentView that returns nullptr (instead of the view itself)
when no children cover the target point. This makes GetHitTestResult return kOther,
allowing hitTest: to fall through to [super hitTest:] and find
RenderWidgetHostViewCocoa. This also removes the now-unnecessary chromium
partial-revert patch that worked around the same issue.

+## API History Migration
+

+Style rules: `docs/development/style-guide.md` (see "API History" section)
+Schema: `docs/api-history.schema.json`
+Lint: `npm run lint:api-history`
+
+### Format
+
+Place YAML history block directly after the Markdown header, before parameters:
+
+````md
+### `module.method(args)`
+
+<!--
+```YAML history
+added:
+  - pr-url: https://github.com/electron/electron/pull/XXXXX
+```
+-->
+
+* `arg` type - Description.
+````
+
+### Finding when an API was added
+
+- `git log --all --reverse --oneline -S "methodName" -- docs/api/file.md` — find first commit adding a method name
+- `git log --reverse -L :FunctionName:path/to/source.cc` — trace C++ implementation history
+- `git log --grep="keyword" --oneline` — find merge commits referencing PRs
+- `gh pr view <number> --repo electron/electron --json baseRefName` — verify PR targets main (not a backport)
+- Always use the main-branch PR URL in history blocks, not backport PRs
+
+### Cross-referencing breaking changes
+
+- Search `docs/breaking-changes.md` for the API name to find deprecations/removals
+- Use `git blame` on the breaking-changes entry to find the associated PR
+- Add `breaking-changes-header` field using the heading ID from breaking-changes.md
+
+### Placement rules
+
+- Only add blocks to actual API entries (methods, events, properties with backtick signatures)
+- Do NOT add blocks to section headers like `## Methods`, `### Instance Methods`, `## Events`
+- Module-level blocks go after the `# moduleName` heading, before the module description quote
+- For changes affecting multiple APIs, add a block under each affected top-level heading (see style guide "Change affecting multiple APIs")
+
+### Key details
+
+- `added` and `deprecated` arrays have `maxItems: 1`; `changes` can have multiple items
+- `changes` entries require a `description` field; `added`/`deprecated` do not
+- Wrap descriptions in double quotes to avoid YAML parsing issues with special characters
+- Early Electron APIs (pre-2015) use merge-commit PRs (e.g., `Merge pull request #534`)
+- Very early APIs (2013-2014, e.g., `ipcMain.on`, `ipcRenderer.send`) predate GitHub PRs — skip history blocks for these
+- When multiple APIs were added in the same PR, they all reference the same PR URL
+- Promisification PRs (e.g., #17355) count as `changes` entries with a description
+  - These PRs are breaking changes and should have their notes as "This method now returns a Promise instead of using a callback function."
+- APIs that were deprecated and then removed from docs don't need history blocks (the removal is in `breaking-changes.md`)

+# Run the init script where you want to clone the project and point it to your fork:
+e init --fork my-org/electron --bootstrap testing

+
+This will create a new `electron` folder in your working directory and initialize the project.
+Once the build completes, navigate to `electron/src/electron`, where your fork is actually cloned.

+> usage instructions (e.g. how to sync dependencies or how to recompile the binary)

-Subject: build: partially revert Mac fullscreen top-chrome mouse events
-
-Reverts "mac: fix missing mouse up and down event in fullscreen top-chrome".
-This CL caused all interactions to fail when loading a page via loadURL
-on Mac. This patch can be removed when upstream is fixed, or when a better
-solution is put in place.
-
-This reverts commit 8c004781dde7d42d9a3fed8cafcaa4929943dd69.

+Subject: fix: restore sdk_inputs cross-toolchain deps for macOS
+
+The change in CL:7652975 restricted sdk_inputs public_deps
+to iOS only, to avoid setting up Xcode symlinks for the Linux
+toolchain when cross-building chrome/linux on Mac. However, this
+also broke cross-arch macOS builds (e.g. ffmpeg with target_cpu=x64)
+where the mig target in the clang_arm64 toolchain depends on
+sdk_inputs from the default clang_x64 toolchain.
+
+Add target_os == \"mac\" alongside the existing iOS check to preserve
+the original intent while restoring the cross-toolchain dependency
+for macOS builds.
+
+We should try to upstream this.

+Subject: fix: prefer browser runtime over node in HostRuntime detection
+
+In Electron, the `process` global is available in renderer processes,
+including the DevTools renderer. This causes the IS_NODE check to pass,
+leading DevTools to attempt importing the Node.js platform runtime
+(which uses `node:worker_threads`). However, DevTools Web Workers
+running under the `devtools://` protocol don't have access to Node.js
+built-in modules, resulting in a failed dynamic import.
+
+Fix by checking IS_BROWSER first, since DevTools always runs in a
+browser-like environment. The Node.js runtime is only needed when
+DevTools runs under pure Node.js (e.g., CLI tooling or testing).
