kami 7bcad64398 fix(orchestrator): wire TASK.md writing and §6.2 pickup validation (B6, partial)
Fixes AUDIT.md's B6: nothing wrote a TASK.md into a worktree, so
continuity.ValidatePickup had no caller and no file to check.

- continuity.RenderTaskFile/TaskFileHash: render and hash the immutable
  §6.2 TASK.md from a domain.Task.
- GitWorktrees.Create writes and commits TASK.md into every freshly
  created worktree (must be committed, not dirty, for ScratchCommit's
  immutability check and for a stable hash).
- Coordinator.Start now runs continuity.ValidatePickup (anchor SHA,
  dirty-file hashes, TASK.md hash) against the real worktree before
  bootstrapping a successor onto a handoff_ref, and blocks the task
  instead of bootstrapping on a validation failure.

Still open from Phase 4: handoff production (agent writing the real
handoff; Release still refuses per B5), ScratchCommit wiring before
release, and the §6.2 bootstrap-prompt rewrite — see AUDIT.md.
