feat(close): add /close skill for session-end memory ritual

Manual fallback for the 3-question ritual (what was decided / learned / blocked) when none of the completion skills ran. Pre-fills BDR/LRN/ BLK candidates from git log + conversation context, presents for validation, appends approved entries to .claude/memory/ registries plus a timeline line in journal.md. Always writes the journal line even if all 3 questions are skipped. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

+  End-of-session ritual — capitalize the 3 registry questions: what was
+  decided, what was learned, what was blocked. Writes approved entries
+  into `.claude/memory/decisions.md`, `.claude/memory/learnings.md`, and
+  `.claude/memory/blockers.md`, plus a timeline line in `.claude/memory/journal.md`.
+  Trigger: "close", "end session", "ferme la session", "session close",
+  "checkpoint memory", "what did we learn", "retro rapide", "fin de journée".

+# CLOSE — Session-Close Ritual
+
+Capture the 3 registry-worthy outputs from the current session before losing context. Operates entirely on conversation memory + git state — does NOT re-read code.
+
+## STEP 0 — PRECHECK
+
+Verify the registry files exist:
+
+```bash
+ls .claude/memory/decisions.md .claude/memory/learnings.md .claude/memory/blockers.md .claude/memory/journal.md 2>/dev/null
+```
+
+- If `.claude/memory/` is missing entirely → print:
+  ```
+  ⚠️  .claude/memory/ absent. Lance d'abord `/onboard` (ou `/init-project` pour un nouveau repo)
+     pour créer la structure des registres.
+  ```
+  STOP.
+- If some files are missing → print which, create them from `~/.claude/templates/memory/<name>.md`, continue.
+
+## STEP 1 — GATHER SESSION CONTEXT
+
+Collect the raw material without re-reading code:
+
+```bash
+git log --oneline -10
+git diff HEAD --stat
+git status --short
+date +%Y-%m-%d
+```
+
+Extract from current conversation:
+- Any decision made (framework pick, refactor scope, architecture choice, naming convention).
+- Any learning surfaced (surprising API behaviour, reusable pattern, gotcha, "don't do X").
+- Any blocker encountered (dead end, friction > 15 min wasted, upstream bug).
+
+## STEP 2 — THE 3 QUESTIONS
+
+Present the ritual compactly — one screen, 3 questions, pre-filled draft answers from STEP 1:
+
+```
+═══ SESSION-CLOSE RITUAL — 3 QUESTIONS ═══
+
+1️⃣  Qu'est-ce que tu as décidé ?
+    Proposition BDR-XXX :
+      Titre   : <extrait de la conversation>
+      Décision: <1 phrase>
+      Pourquoi: <1-2 phrases>
+      Alts rejetées: <si captable>
+    → (accept / edit / skip / add another)
+
+2️⃣  Qu'est-ce que tu as appris ?
+    Proposition LRN-XXX :
+      Pattern : <extrait abstrait>
+      Contexte: <où/quand>
+      Future  : <quand s'en rappeler>
+    → (accept / edit / skip / add another)
+
+3️⃣  Sur quoi es-tu bloqué ?
+    Proposition BLK-XXX :
+      Friction   : <extrait>
+      Cause      : <si identifiée — sinon "à investiguer">
+      Solution   : <workaround si déjà trouvé — sinon "open">
+      Statut     : open | resolved | upstream
+    → (accept / edit / skip / add another)
+
+Action globale ? (all / pick <numbers> / edit / skip-all)
+```
+
+If nothing notable to propose for a given question → say `(rien à logger cette session)` for that question.
+
+## STEP 3 — WRITE APPROVED ENTRIES
+
+For each approved entry:
+
+1. Read the target registry file.
+2. Append the new entry at the end (never rewrite existing entries).
+3. Add a line to the Index table at the top with the new ID, date, short title, status.
+4. Generate next sequential ID by scanning existing IDs (e.g., if `BDR-007` exists, next is `BDR-008`).
+
+## STEP 4 — JOURNAL ENTRY
+
+Always write one line in `.claude/memory/journal.md` under today's heading — even if all 3 questions were skipped:
+
+- If today's heading exists → append a new bullet under it.
+- If not → create `## YYYY-MM-DD` heading and write 3-5 bullets summarising the session.
+
+Template:
+```markdown
+## YYYY-MM-DD
+
+- <what was done — 1 line from conversation>
+- <what was decided — link to BDR-XXX if logged>
+- <what was learned — link to LRN-XXX if logged>
+- <what's blocked — link to BLK-XXX if logged>
+- <commit hashes if any — `<hash1>..<hashN>`>
+```
+
+## STEP 5 — FINAL OUTPUT
+
+```
+CLOSE COMPLETE — session <YYYY-MM-DD>
+  decisions.md  : +<N> entries (BDR-XXX, BDR-YYY)  |  0 entries
+  learnings.md  : +<N> entries (LRN-XXX)           |  0 entries
+  blockers.md   : +<N> entries (BLK-XXX)           |  0 entries
+  journal.md    : +1 line under ## <date>
+Prochaine session : lire `.claude/memory/` au démarrage pour rappel.
+```
+
+---
+
+## RULES
+
+- Never invent content. Every entry must be grounded in the current conversation or git history — no fabricated "lessons".
+- Skip silently rather than log a trivial entry. Journal excepted (timeline logging is cheap, noise is fine).
+- Never overwrite existing entries — append-only.
+- If the user says `skip-all` → still write the journal line and exit.
+- If `.claude/memory/` is missing → STOP at STEP 0, do not create it here (onboard / init-project responsibility).
