feat(skills): add dev-team skill — multi-persona collaborative session (#2309)

* feat(skills): add dev-team skill — multi-persona collaborative session

Adds skills/dev-team/SKILL.md, a community skill inspired by the
BMAD Method's "party mode": PM, Architect, Developer, and QA respond
to the same topic in parallel, then a synthesis step names tensions
explicitly instead of averaging them.

Reads PROJECT-CONTEXT.md from the repo root when present, and offers
to generate it when missing, folding in the closed project-context
skill's (#2310) generation workflow per affaan-m's review — that
skill's premise (every agent reads the file) wasn't implemented
anywhere, so the capability now lives directly in the one skill that
actually reads it.

Rebuilt on current upstream/main as a skill-only diff: the shared
format-code.ts Windows fix and github-coordination branch-coverage
tests that were previously bundled here (and duplicated across the
story-lifecycle and project-context sibling PRs) now live in #2459.

* fix(manifests): register dev-team skill in workflow-quality install module

* fix(docs): repair README lint errors and Windows hook-install path regression

Fixes CI inherited from the README 2.1 restructure (19b05476):
- MD058: blank lines around tables (delegation map, Codex role configs)
- MD001: Option A/B headings under Ecosystem Tools h2 jump to h4
- MD024: duplicate 'What's included' headings (Codex, Copilot sections)
- restore %USERPROFILE%\\.claude escaping required by
  tests/scripts/manual-hook-install-docs.test.js

* feat(skills): address review — trust boundary, harness-neutral I/O, contract test

Address maintainer review on #2309:
- untrusted-context boundary now travels with every persona prompt:
  inline label on the context section, personas marked analysis-only
  with no state-changing tool use
- personas receive a bounded declarative summary (≤150 words, fixed
  fields, secrets and imperative content stripped) — never the raw
  PROJECT-CONTEXT.md
- context loading uses harness-native file tools; POSIX-only
  'test -f && cat' removed
- all references resolve on main: story-lifecycle follow-up replaced
  with /plan and epic-* commands, ecc:plan-prd corrected to the
  /plan-prd command; boundary vs team-builder and council made explicit
- added tests/docs/dev-team-skill.test.js contract test (roles,
  parallel dispatch, synthesis guardrails, trust boundary, registration)

* docs: refresh Turkish skill count

* ci: retrigger checks (flaky stop-hooks-stdout timeout on macos node20 npm cell)
