feat(fish): 🎣 Add fzf key bindings integration

Add fzf key bindings function file with support for:
- File search widget (Ctrl+T)
- Command history search (Ctrl+R) (replaced by custom implementation)
- Directory navigation (Alt+C) (replaced by custom implementation)

Bindings work in both normal and insert modes, providing
fuzzy search capabilities for fish shell navigation and
command history.
