fix: Prevent FileSystemWatcher leak in RooIgnoreController

[kiwina]

PR for RooIgnoreController FileSystemWatcher Leak (RooIgnoreController_41)

This PR addresses the FileSystemWatcher leak associated with RooIgnoreController as identified in leak-report/guaranteed/RooIgnoreController_41.md.

Description

RooIgnoreController instances, created by Task objects, manage a FileSystemWatcher. If a Task is not properly disposed of (i.e., Task.abortTask() or a new Task.dispose() method isn't called reliably), the RooIgnoreController's dispose method isn't called, leading to its FileSystemWatcher leaking.

This patch focuses on ensuring the Task class has a robust dispose method that cleans up its RooIgnoreController, and that Task.abortTask() reliably calls this dispose method.

Closes: #4232

Changes

• Added/Augmented dispose() method in src/core/task/Task.ts to explicitly call this.rooIgnoreController?.dispose().
• Ensured Task.abortTask() calls the new/augmented this.dispose() method.
• Verified that ClineProvider.removeClineFromStack() correctly calls task.abortTask() or task.dispose().
• Add/update unit tests if applicable to verify the disposal chain for Task and RooIgnoreController.

How to Test

1. Create scenarios where Task instances are created and then their parent ClineProvider is disposed of or individual tasks are removed from the stack.
2. Verify through logging or debugging that RooIgnoreController.dispose() is called for each RooIgnoreController instance associated with a cleaned-up Task.
3. Monitor for any "Can't perform a React state update on an unmounted component" warnings related to FileSystemWatcher callbacks if test components are involved.

Important

Fixes FileSystemWatcher leak in RooIgnoreController by ensuring Task.dispose() is called for cleanup in Task.ts.

• Behavior:
  • Fixes FileSystemWatcher leak in RooIgnoreController by ensuring dispose() is called.
  • Task.dispose() method in Task.ts now cleans up RooIgnoreController and other resources.
  • Task.abortTask() in Task.ts calls dispose() to ensure cleanup.
• Testing:
  • Verify RooIgnoreController.dispose() is called when Task is disposed or aborted.
  • Monitor for React state update warnings related to FileSystemWatcher during tests.

LGTM, I tested normal tasks and subtask, everything seems to be working as expected and no shared resources are being disposed.

One test failed, however doesn't seem to be related to this PR, I reran it but it got cancelled.

Thank you @kiwina!
