Steve Yegge 57917521e6 fix: migrate gt mail to use bd v0.32.0 issue commands
bd v0.32.0 removed mail commands. Updated gt mail to use:
- bd list --type message (inbox)
- bd show (read)
- bd close (delete/ack)
- bd create --type message (send)

Sender/thread/reply-to now stored in labels and extracted on read.
Added --pinned flag (blocked by bd pin bug gt-zr0a).
