feat(using-projects-meta): v1.1.0 — mandatory Step 0 freshness gate

Cross-machine workflows broke silently when the agent reasoned on a stale
MCP cache, or hit sha-based optimistic-lock 422s on shared-wiki writes
because another host had pushed minutes earlier. Codify the missing
pre-flight as Step 0:

  1. Always probe mcp__projects-meta__meta_status first.
  2. If cache_age_minutes > 10 OR errors_count > 0 → run
     `node ~/.local/projects-meta-mcp/dist/sync.js` before any read.
  3. For shared-wiki WRITES (knowledge_ingest, knowledge_promote) →
     unconditional `git -C ~/projects/projects-wiki pull --ff-only`
     (sha-lock will reject the commit otherwise; failure is opaque).
  4. Tasks-mutations: sync via dist/sync.js is enough (no local clone
     of target tasks repo).
  5. Sync 401/403 → STOP, send user to ~/.config/projects-mcp/auth.toml
     to rotate gitea_token. No silent retry.

10-minute cache window chosen as the read threshold — balances
multi-machine drift detection against unnecessary Gitea round-trips.

Common mistakes + Red flags expanded to call out the new failure modes.
README mirrors the rule for human readers. Wiki concept page
projects-meta-skills.md gets a "Freshness gate (v1.1.0)" subsection.

Closes [using-projects-meta-freshness-gate].

+## 🟢 [using-projects-meta-freshness-gate] — добавить Step 0 freshness check в using-projects-meta
+
+**Status:** done
+**Where I stopped:** Step 0 добавлен в `using-projects-meta/SKILL.md` (cache_age>10мин или errors>0 → `dist/sync.js` для read; shared-wiki write — безусловный `git pull --ff-only`; 401/403 → auth.toml rotation); зеркалирован в README; bump 1.0.0→1.1.0; rebuild+install OK; description trimmed до 924 chars после регрессии (полное Step 0 в description ~1450 chars сломало парсинг — harness зафолбэкнулся на H1, скилл потерял все триггеры); Common mistakes + Red flags расширены; concept page + log обновлены; new feedback memory `skill_description_length_limit`
+**Next action:** (none — kept until merged)
+**Branch:** master
