feat(cmd): add desire-path commands for agent ergonomics

- gt hook --clear: alias for 'gt unhook' (gt-eod2iv)
- gt close: wrapper for 'bd close' (gt-msak6o)
- gt bead move: move beads between repos (gt-dzdbr7)

These commands were natural guesses that agents tried but didn't exist.
Following the desire-paths approach to improve agent ergonomics.
