Sync bundled mission-control to upstream 15fbc94

Pulls in 15 upstream commits since the April 3 bundling snapshot
(msieurthenardier/mission-control). Notable changes:

- agentic-workflow rewritten as the "fast" variant: per-leg design and
  implement, single review and commit across the whole flight
- New Skill-Project Boundary section: skills no longer read or write
  project-owned artifacts by literal heading
- routine-maintenance scoped to post-mission only; adds state-machine
  reachability and cache freshness audits
- Test metrics capture threaded through debrief, maintenance, and flight
- Crew prompts no longer carry skill-required instructions; SKILL.md is
  the protocol
- Worktree git strategy removed; standardized on {target-project}
- Jira artifact template removed upstream

Local URL correction in init-project/README.md preserved
(anthropics/flight-control -> msieurthenardier/mission-control).
