Add gt hook status alias for gt mol status

Makes 'gt hook' (no args) show hook status instead of requiring a bead ID.
Also adds 'gt hook status' subcommand for explicit usage. The hook concept
is user-facing while molecules are implementation details.

 The hook is the "durability primitive" - work on your hook survives session
 restarts, context compaction, and handoffs. When you restart (via gt handoff),
 your SessionStart hook finds the attached work and you continue from where
 you left off.
 
-This is "assign without action" - use gt sling to also start immediately,
-or gt handoff to hook and restart with fresh context.

 Examples:
+  gt hook                           # Show what's on my hook
+  gt hook status                    # Same as above
