refactor: replace lazy zoxide with eager init and add fd-based directory discovery

- Switch from lazy-loaded z/zi to eager zoxide initialization in config.fish
- Alias cd to use zoxide for automatic frecency tracking
- Add Alt+D: discover directories from git root/cwd with fd+fzf (no gitignore)
- Add Alt+Shift+D: discover directories from HOME with fd+fzf (depth 5)
