docs(handoffs): add 2026-05-18 session handoffs

[JustAGhosT]

Summary

Adds two handoff documents from the 2026-05-18 workspace hygiene work:

• 2026-05-18.md — original session: PR chore(gitignore): ignore .claude/scheduled_tasks.lock #556 (gitignore + prettier), repo branch cleanup (5 stale local + 44 cross-repo merged), 4 orphan worktree removals, baton MCP Accept-header fix, Linear audit.
• 2026-05-18-02.md — follow-up session: executed all three recommended next actions.
  • Baton MCP fix confirmed present in ~/.claude.json; restart still pending.
  • Mystira-workspace: 3 worktrees triaged. Sluice WIP preserved as draft PR phoenixvc/mystira-workspace#1654; 2 scratch worktrees removed.
  • Linear: PHO-5 → Done (PR fix(ci): remediate failing workflows on main and dev branches #377 merged 2026-03-21), COD-13 → Backlog with missing-info checklist.

Test plan

• Files render correctly in the docs/handoffs/ directory listing
• Both files follow the existing handoff template (date, branch, last commit, scope, status, next actions, validation, risks, state files)
• No secrets or credentials in the diff

Summary by CodeRabbit

• Documentation
  • Added developer handoff notes summarizing a dev-branch session: checklist of next actions (service restart, ticket reconciliation, workspace triage), completed housekeeping (branch/workspace cleanup and stale-file removal), and open risks/validation steps for ongoing work.

📝 Walkthrough

Walkthrough

Two handoff documents are added to track a dev-branch session. The initial handoff records session scope, completed hygiene work, current blockers, next actions, and open risks. The continuation handoff documents completion of follow-up work: Baton MCP header verification, Mystira-workspace worktree consolidation, and Linear ticket reconciliation.

Poem

A rabbit hops through session notes,
Recording what the dev branch wrote—
MCP headers checked and worktrees neat,
Linear tickets moved to tidy seats.
The handoff closes, next steps clear and bright. 🐰📋
