feat,refactor: rework getHistory, return Notification objects

Add static methods for managing delivered notifications via the
UNUserNotificationCenter API:
- getHistory() returns all delivered notifications still in Notification Center
- remove(id) removes one or more notifications by identifier
- removeAll() removes all delivered notifications

These methods build on the custom id support to enable full notification
lifecycle management from the main process.

+## API History Migration
+
+Guide: `docs/development/api-history-migration-guide.md`
+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`)

+#### `Notification.getHistory()` _macOS_
+
+Returns `Promise<Notification[]>` - Resolves with an array of `Notification` objects representing all delivered notifications still present in Notification Center.
+
+Each returned `Notification` is a live object connected to the corresponding delivered notification. Interaction events (`click`, `reply`, `action`, `close`) will fire on these objects when the user interacts with the notification in Notification Center. This is useful after an app restart to re-attach event handlers to notifications from a previous session.
+
+The returned notifications have their `id`, `groupId`, `title`, `subtitle`, and `body` properties populated from what macOS provides. Other properties (e.g., `actions`, `silent`, `icon`) are not available from delivered notifications and will have default values.
+
+> [!NOTE]
+> Like all macOS notification APIs, this method requires the application to be
+> code-signed. In unsigned development builds, notifications are not delivered
+> to Notification Center and this method will resolve with an empty array.
+
+> [!NOTE]
+> Unlike notifications created with `new Notification()`, notifications returned
+> by `getHistory()` will remain visible in Notification Center when the object
+> is garbage collected.

+npm install -g @electron/build-tools
+# 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.

+> Your Electron project has a complex folder structure with nested repositories.
+> See the [Build Instructions](./build-instructions-gn.md) docs for detailed Build Tools
+> usage instructions (e.g. how to sync dependencies or how to recompile the binary)
+> and platform-specific notices.
+
+There, you should have two `remote` URLs in git:

-```shell
-npm install --arch=x64 electron

+* `arm64` (Apple silicon, Windows on ARM, ARM64 Linux)
+* `arm` (32-bit ARM)

 In addition to changing the architecture, you can also specify the platform
 (e.g., `win32`, `linux`, etc.) using the `--platform` flag:

+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).
+
