feat: add interactive fzf tools for chezmoi apply/show with shared utilities

- New chai function for interactive apply with multi-select and diff preview
- Enhanced chshow for browsing managed files with edit/view modes
- Shared fzf-utils.ts with standardized colors and chezmoi file parsing
- Bash version of fzf abbreviation search with Alt+A binding
