… graph scope picker - W-22201120 (#386)

* feat(apex-lsp-extension): replace workspace load toast with status bar spinner - W-22201120

Replace vscode.window.withProgress notification with status bar updates
during workspace loading. The spinner persists until the server sends
apex/workspaceIngestionComplete, giving accurate feedback on server-side
processing time.

- Add updateApexServerStatusLoading() to status-bar.ts
- Register apex/workspaceIngestionComplete handler on web + desktop clients
- Pass workerPlatformWebUrl in initialization options for web workers
- Flatten workspace-loader async flow, remove cancellation token handling
- Add .sf/** to exclude glob, support maxFileCount in development mode
- Default findFilesAcrossWorkspaceFolders maxResults to Infinity

* feat(apex-lsp-extension): add worker topology UI and graph scope picker - W-22201120

Add extension-side UI for monitoring and configuring the worker topology:

- performanceSettingsScript: add Experimental Workers section with enable
  toggle, pool size, and resource loader controls
- queueStateScript: render worker topology cards with role status indicators
  and coordinator/worker dispatch tags on request types
- showGraph: add QuickPick scope chooser (Current File vs All Types)
- showPerformanceSettings: persist experimental.workers settings
- server-config: pre-create per-role profiling subdirectories for workers

* feat(apex-lsp-web): expose worker topology status in queue state metrics - W-22201120

Inject workerTopology from the WorkerCoordinator dispatcher into both the
apex/queueState request response and the periodic apex/queueStateChanged
notification. This enables the queue state dashboard to render live worker
role cards and dispatch indicators.

* refactor(apex-lsp-extension): extract shared ingestion complete handler

De-duplicate the apex/workspaceIngestionComplete notification handler
that was registered identically in both createWebLanguageClient and
createDesktopLanguageClient into a single registerIngestionCompleteHandler
helper.

* fix(apex-lsp-extension): exclude .sf directories at any workspace depth

The exclude glob template already wraps entries with **/{...}/**,
so the entry should be just '.sf' (not '.sf/**') to produce the
correct pattern **/.sf/** matching .sf directories at any level.

* fix(apex-lsp-extension): add 5-minute timeout for ingestion complete notification

If the server crashes or fails to send apex/workspaceIngestionComplete,
the status bar spinner would spin indefinitely. Add a 5-minute timeout
that falls back to ready state and logs a warning.

* refactor(apex-lsp-extension): type renderExperimentalWorkers parameter

Replace 'any' with ExperimentalSettings interface for the
renderExperimentalWorkers method parameter. Add ExperimentalSettings
and ExperimentalWorkersSettings interfaces to the webview script.

* fix(apex-lsp-extension): correct worker topology default in help text

The fallback when no setting exists is enabled: true, so the help text
should say "(default: on)" not "(default: off)".

* fix(apex-ls): improve type safety in worker topology integration

- Narrow the 'as any' cast in queueState handler to a proper type
  assertion (Record<string, unknown>) after the 'metrics' in-check
- Align coordinatorOnlyTypes to 'readonly string[]' on both server
  and client interfaces
- Move enrichedMetrics computation after the log statement that
  references the original metrics to reduce confusion

* fix: lint

* fix: address review suggestions for worker topology PR (#387)

- Avoid in-place mutation of metrics result in LCSAdapter by using spread
- Pass undefined instead of Infinity to vscode.workspace.findFiles API
- Replace non-null assertion with optional chaining in showGraph
- Clear ingestion timeout on server stop to prevent stale timer firing

* fix: stuck on browser download for unit tests
