Mission Run: Analysis Report Coord-Worktree Fix & Recovery UX

Fix record-analysis to succeed under coord-worktree topology and emit actionable recovery guidance when analysis-report.md is in carrier format.

When a coordination worktree is active, record-analysis resolves the mission directory to the coord-worktree path, where spec.md is absent, causing it to fail. Agents forced to write analysis-report.md directly use the carrier format, which the implement gate rejects with a cryptic error. This mission fixes the write-path anchor, adds a named error code for the carrier-format case, and surfaces exact recovery commands so agents can unblock themselves.
