Skill System TKT

Single source of truth for all ticket operations across the skill system.

Two Backends, One Lifecycle

Backend 1: Filesystem Bundles (tkt.sh)
  Project-level work management.
  Roadmap → Bundle → Tickets (YAML files in .tkt/)
  Use for: PM-driven decomposition, multi-agent bundles, review generation.

Backend 2: DB Durable Tickets (tickets.py)
  Session-level lifecycle management.
  Intake → Claim → Work → Block/Close (Postgres agent_memories)
  Use for: claim arbitration, session loops, scope enforcement, refresh.
