## Title

    Proposed fix: [Linux inotify] 'ENOSPC: System limit for number of file watchers reached' from Node fs.watch / dev servers / VS Code — inotify max_user_watches exhausted, not disk space

## Body

    Recommended action: First exclude large folders from watching (e.g. files.watcherExclude for .venv/node_modules, watcher ignore options); if still needed, raise fs.inotify.max_user_watches (e.g. 524288) persistently via /etc/sysctl.conf or /etc/sysctl.d/*.conf and `sudo sysctl --system`.
    
    Option: Reduce watched files, then raise max_user_watches [evidence: official_recommended_action]
    Applies when: Linux/WSL2 dev machines
    Steps:
    1. Exclude node_modules/.venv/build dirs from watchers
    2. cat /proc/sys/fs/inotify/max_user_watches to see current value
    3. Add fs.inotify.max_user_watches=524288 to /etc/sysctl.conf or a file in /etc/sysctl.d/
    4. sudo sysctl --system
    Expected: Watcher starts without ENOSPC
