docs: trim CLAUDE.md 66.4→44.9KB — verbatim moves to docs/, pointers stay inline

Moved: browser/sidebar/server internals, CHANGELOG release-summary format
spec, project tree, hermetic-E2E detail, slop-scan reference, OpenClaw
publishing. Kept inline: every hard behavioral rule (dist/ ban, redaction
scan-at-sink, egress receipts, bisect commits, eval detach, CHANGELOG
entry rules), the machine-managed GBrain block (byte-identical), and the
'## Deploying to the active skill' header with gbrain-refresh in range
(pinned by test/gbrain-refresh-install-render.test.ts). No voice rewrites.

+# Publishing native OpenClaw skills to ClawHub
+
+Moved verbatim from CLAUDE.md (token-load reduction).
+
+## Workflow
+
+Native OpenClaw skills live in `openclaw/skills/gstack-openclaw-*/SKILL.md`. These are
+hand-crafted methodology skills (not generated by the pipeline) published to ClawHub
+so any OpenClaw user can install them.
+
+**Publishing:** The command is `clawhub publish` (NOT `clawhub skill publish`):
+
+```bash
+clawhub publish openclaw/skills/gstack-openclaw-office-hours \
+  --slug gstack-openclaw-office-hours --name "gstack Office Hours" \
+  --version 1.0.0 --changelog "description of changes"
+```
+
+Repeat for each skill: `gstack-openclaw-ceo-review`, `gstack-openclaw-investigate`,
+`gstack-openclaw-retro`. Bump `--version` on each update.
+
+**Auth:** `clawhub login` (opens browser for GitHub auth). `clawhub whoami` to verify.
+
+**Updating:** Same `clawhub publish` command with a higher `--version` and `--changelog`.
+
+**Verification:** `clawhub search gstack` to confirm they're live.
