feat(skills): add captain-invocable bearings status-report skill

Situation

• Compliance: pass
• Tests: green
• Notes: compliance=pass tests=green

Triage

• Summary: Adds a new captain-invocable /bearings skill (SKILL.md) that composes a dated status report from live fleet state (backlog, per-task crew state, open PRs, scout reports, pending decisions, date-gated queue) and lists it in the README skills table.
• Product implications: Routine internal work: a single self-contained, read-mostly documentation/skill file matching sibling conventions (frontmatter style verified against afk/updatefirstmate), referencing an existing script (bin/fm-crew-state.sh), with no executable code or product-behavior change - no owner discussion needed.
• Recommended next step: merge - low-risk doc-only skill addition, matches house conventions, deliberate scope constraints (no AGENTS.md edit, no helper script) are followed.

Recommended action

Merge - compliance and tests are green.
