v0.12.0

New

• --priority on tk add, tk update, and tk accept now accepts lowercase and bare ranks (p2, 2) alongside P2; the rejection message lists the accepted forms.
• The Pi extension installs as a package with pi install git:github.com/lithammer/tk (add --local for one project).

Improved

• tk list keeps a done Epic as context in every view when one of its Tickets matches, so grouped Tickets never lose their Epic; done Epics without matching children stay hidden.
• man tk now documents every command, derived from the CLI itself, with extended behaviour and recovery guidance beside each.
• Command-error prefixes on stderr follow the colour policy (NO_COLOR, CLICOLOR_FORCE, TTY detection), making failures easier to spot.

Fixed

• The tk sync banner now colours Epic and Ticket Mutations with the right palette entry instead of guessing from the Display ID.
