Make watch() async

[mendral-app]

Summary

• Convert watch() method in default/filesystem.py from def to async def so that asyncio.create_task() is always called within a running event loop, eliminating RuntimeError: no running event loop when called from non-async contexts.

Context

Resolves insight: Async watch() called without running event loop

Note

This is a breaking API change — callers must now await sandbox.fs.watch(...) instead of calling it directly. Most users are already in async contexts since the return type is AsyncWatchHandle.

@Mendral are you sure? It won't break an user which was using the sync method?
