fix(watcher): remove debug logging that corrupts TUI

Remove charmbracelet/log debug statements from the file watcher that
were writing directly to stderr, corrupting the Bubble Tea terminal UI.

- Remove log.Debug calls for directory operations and file changes
- Remove log.Warn for watcher errors (silently ignore instead)
- Remove the charmbracelet/log import entirely
