Subject: [PATCH] fix(handoff): recognize polecat session pattern
 gt-<rig>-<name> (#373)

sessionWorkDir had cases for mayor, deacon, crew, witness, and refinery
but not polecats. When gt handoff was run from a polecat session like
gt-tanwa_info-slit, it failed with "unknown session type".

Fix uses session.ParseSessionName to parse the session name and extract
rig/name for polecat sessions, mapping to <townRoot>/<rig>/polecats/<name>.

Fixes: gm-lie6
