feat: OpenClaw integration v2 — prompt is the bridge (v0.15.9.0) (#816)

* feat: add includeSkills to HostConfig + update OpenClaw config

Add includeSkills allowlist field with union logic (include minus skip).
Update OpenClaw to generate only 4 native methodology skills (office-hours,
plan-ceo-review, investigate, retro). Remove staticFiles.SOUL.md reference
(pointed to non-existent file).

* feat: OpenClaw integration — gstack-lite/full generation + spawned session detection

Add includeSkills filter to gen-skill-docs pipeline. Generate gstack-lite
(planning discipline for spawned coding sessions) and gstack-full (complete
feature pipeline) for OpenClaw host. Add OPENCLAW_SESSION env var detection
in preamble for spawned session auto-detect. Update setup --host openclaw
to print redirect message.

* docs: OpenClaw architecture doc + regenerate all SKILL.md with spawned session detection

Add docs/OPENCLAW.md with 4-tier dispatch routing and integration architecture.
Generate gstack-lite and gstack-full prompt templates. Regenerate all SKILL.md
files with OPENCLAW_SESSION env var check in preamble.

* test: update golden baselines + OpenClaw includeSkills tests

Update golden SKILL.md baselines for preamble SPAWNED_SESSION change.
Replace staticFiles SOUL.md test with includeSkills validation.

* chore: bump version and changelog (v0.15.9.0)

* fix: remove all Wintermute references from source files

Replace with generic "orchestrator" or "OpenClaw" as appropriate.

* feat: add Plan dispatch tier — full review gauntlet for Claude Code project planning

New gstack-plan template chains /office-hours → /autoplan (CEO + eng + design + DX
+ codex adversarial), saves the reviewed plan, and reports back to the orchestrator.
The orchestrator persists the plan link to its own memory store. 5 tiers now:
Simple, Medium, Heavy, Full, Plan.
