Fix folder watcher matching, notifications, and BLM venv isolation

- Remove status filter from folder watcher so tasks in any open status
  (including "internal review") are matched by keyword
- Add retry logic for stuck processing/blocked/unmatched KV states
- Fix notification ordering (newest first, limit 50) and date parsing
- Use BLM's own .venv Python instead of uv run for subprocess calls
- Document external tools venv convention in CLAUDE.md

 - **Notifications**: All scheduler events go through `NotificationBus.push()`, never directly to a UI
 - **Tests**: Use `respx` to mock httpx calls, `tmp_db` fixture for isolated SQLite instances
 - **ClickUp attachments**: `ClickUpClient.upload_attachment()` uses module-level `httpx.post()` (not the shared client) for multipart uploads
+- **External tools**: Subprocess calls to external projects (e.g. Big-Link-Man) must use the tool's own `.venv` Python, never `uv run` from CheddahBot's environment. Resolve the venv python at `{tool_dir}/.venv/Scripts/python.exe` (Windows) or `{tool_dir}/.venv/bin/python` (Linux/Mac). Fail if no venv exists.
