Release v0.2.0: Context Resilience, AskUserQuestion, /design-systems

* Add context resilience: file-backed state, incremental writing, auto-recovery

Prevents "prompt too long" crashes from killing sessions by persisting work
to disk incrementally instead of relying on conversation memory.

Changes:
- pre-compact.sh: dumps session state before context compression
- session-start.sh: detects active.md for crash recovery
- session-stop.sh: archives and clears active.md on clean shutdown
- context-management.md: file-backed state as primary strategy
- 9 agents updated with incremental section writing protocol
  (game-designer, systems-designer, economy-designer, narrative-director,
   level-designer, world-builder, writer, art-director, audio-director)
- CLAUDE.md: trimmed redundant imports (10 → 5) to reduce token overhead
- design-docs.md rule: enforces incremental writing pattern
- .gitignore: excludes ephemeral session state files
- directory-structure.md: documents session-state/ and session-logs/
- COLLABORATIVE-DESIGN-PRINCIPLE.md: documents incremental writing pattern

* Add AskUserQuestion integration across collaborative protocols

Explicitly reference the AskUserQuestion tool in all collaborative agent
definitions, protocol templates, team orchestrator skills, and the master
principle doc. Introduces the Explain-then-Capture pattern: agents write
full expert analysis in conversation, then call AskUserQuestion with
concise labels to capture decisions via structured UI.

26 files updated:
- 3 protocol templates (design, leadership, implementation)
- 14 agent definitions (10 design + 3 leadership + writer)
- 8 orchestrator skills (brainstorm + 7 team-*)
- 1 master principle doc (COLLABORATIVE-DESIGN-PRINCIPLE.md)

* Add /design-systems skill: concept-to-GDD decomposition workflow

Bridges the gap between game concept and per-system design documents.
Professional studios use systems enumeration + dependency sorting between
concept and feature docs — skipping this step is one of the most expensive
mistakes (systems discovered during production cost 5-10x more to add).

New files:
- .claude/skills/design-systems/SKILL.md — 7-phase orchestration skill
  (enumerate systems, map dependencies, assign priorities, write GDDs)
- .claude/docs/templates/systems-index.md — master tracking template

Flow integration (7 existing skills updated):
- brainstorm, start, setup-engine, design-review, gate-check,
  project-stage-detect, game-concept template all reference /design-systems
  at the appropriate workflow touchpoints

* Fix cross-platform bugs, add missing tool permissions, and update docs for v0.2.0

Hooks: fix \s → [[:space:]] in grep -E fallbacks (3 files), fix detect-gaps.sh
empty-variable bug, fix log-agent.sh field name (agent_name → agent_type),
harden validate-push.sh with explicit $MATCHED_BRANCH, convert for-in loops
to while-read for space-safe iteration, add POSIX head -n syntax, increase
PreCompact timeout, widen session-stop log window.

Skills: add AskUserQuestion to 10 skills and TodoWrite to 8 multi-phase skills.
Fix project-stage-detect template/output paths, tech-artist → technical-artist.

Docs: add /design-systems to all references (README, quick-start, workflow guide,
skills-reference), update skill count 35 → 36, remove stale AI artifacts from
COLLABORATIVE-DESIGN-PRINCIPLE.md, add AskUserQuestion note to examples README.

+#### Structured Decision UI
+
+Use the `AskUserQuestion` tool to present decisions as a selectable UI instead of
+plain text. Follow the **Explain → Capture** pattern:
+
+1. **Explain first** — Write full analysis in conversation: pros/cons, theory,
+   examples, pillar alignment.
+2. **Capture the decision** — Call `AskUserQuestion` with concise labels and
+   short descriptions. User picks or types a custom answer.
+
+**Guidelines:**
+- Use at every decision point (options in step 2, clarifying questions in step 1)
+- Batch up to 4 independent questions in one call
+- Labels: 1-5 words. Descriptions: 1 sentence. Add "(Recommended)" to your pick.
+- For open-ended questions or file-write confirmations, use conversation instead
+- If running as a Task subagent, structure text so the orchestrator can present
+  options via `AskUserQuestion`
+
