feat: native OpenClaw skills + ClaHub publishing (v0.15.10.0) (#832)

* feat: add 4 native OpenClaw skills for ClaHub publishing

Hand-crafted methodology skills for the OpenClaw wintermute workspace:
- gstack-openclaw-office-hours (375 lines) — 6 forcing questions, startup + builder modes
- gstack-openclaw-ceo-review (193 lines) — 4 scope modes, 18 cognitive patterns
- gstack-openclaw-investigate (136 lines) — Iron Law, 4-phase debugging
- gstack-openclaw-retro (301 lines) — git analytics, per-person praise/growth

Pure methodology, no gstack infrastructure. All frontmatter uses single-line
inline JSON for OpenClaw parser compatibility.

* feat: add AGENTS.md dispatch section with behavioral rules

Ready-to-paste section for OpenClaw AGENTS.md with 3 iron-clad rules:
1. Always spawn sessions, never redirect user to Claude Code
2. Resolve repo path or ask, don't punt
3. Autoplan runs end-to-end, reports back in chat

Includes full dispatch routing (Simple/Medium/Heavy/Full/Plan tiers).

* chore: clear OpenClaw includeSkills — native skills replace generated

Native ClaHub skills replace the gen-skill-docs pipeline output for
these 4 skills. Updated test to validate empty includeSkills array.

* docs: ClaHub install instructions + dispatch routing rules

- README: add Native OpenClaw Skills section with clawhub install command
- OPENCLAW.md: update dispatch routing with behavioral rules, update
  native skills section to reference ClaHub

* chore: bump version and changelog (v0.15.10.0)

* fix: add gstack-upgrade to OpenClaw dispatch routing

Ensures "upgrade gstack" routes to a Claude Code session with
/gstack-upgrade instead of Wintermute trying to handle it conversationally.

* fix: stop tracking 58MB compiled binary bin/gstack-global-discover

Already in .gitignore but was tracked due to historical mistake.
Same issue as browse/dist/ and design/dist/. The .ts source is right
next to it and ./setup builds from source for every platform.

* test: detect compiled binaries and large files tracked by git

Two new tests in skill-validation:
- No Mach-O or ELF binaries tracked (catches accidental git add of compiled output)
- No files over 2MB tracked (catches bloated binaries sneaking in)

Both print the exact git rm --cached command to fix the issue.

* fix: ClaHub → ClawHub (correct spelling)

* docs: add ClawHub publishing instructions to CLAUDE.md

Documents the clawhub publish command (not clawhub skill publish),
auth flow, version bumping, and verification.
