fix: wrap hook commands in bash -c for paths with spaces

Problem: Claude Code hooks fail when $CLAUDE_PROJECT_DIR contains
spaces (e.g., "Groove Jones Dropbox"). The shell splits the path
on spaces even when quoted in settings.json.

Solution: Wrap all commands using $CLAUDE_PROJECT_DIR in bash -c '...'
so bash handles variable expansion with proper quoting.

Changes:
- Wrapped 25 hooks using $CLAUDE_PROJECT_DIR with bash -c
- Preserved all timeout values
- Left $HOME hooks unchanged (no spaces in home paths)

Pattern applied:
  Before: python3 "$CLAUDE_PROJECT_DIR/.claude/hooks/script.py"
  After:  bash -c 'python3 "$CLAUDE_PROJECT_DIR/.claude/hooks/script.py"'
