fix: use town root beads for Deacon patrol context (gt-sstg)

Deacon is a town-level role, so its beads should be at ctx.TownRoot
(~/gt/.beads/) not ctx.WorkDir (~/gt/deacon/). This fixes the issue
where outputDeaconPatrolContext couldn't find patrol molecules because
it was looking in the wrong location.
