feat(task-loop): new skill for in-session board draining v0.1.0
Interactive claim -> work -> close -> repeat loop in the current session;
no daemon, no spawned claude, no busy-poll. Coordinates with using-tasks
(.tasks/.lock, session_break gate, 10-min claim TTL -> tasks_heartbeat) and
project-discipline (push Rule 4, sensitive artifacts).
TDD (writing-skills RED-GREEN-REFACTOR):
- RED: 2 clean-context subagents revealed gaps A-E (claim scope, missed
session_break + .lock, consult-gate boundary, paused-vs-blocked).
- GREEN: SKILL.md addresses all five; compliance subagent B clean.
- REFACTOR: closed CronCreate loophole in long-watch (separate session =
daemon); mandate ScheduleWakeup on this session. Re-test passed.
Semver: 0.1.0 (initial).
