feat: make docs builder reusable for ClawHub

[Patrick-Erichsen]

Summary

• Makes the generated docs shell read branding, nav links, search suggestions, favicon/logo, OG metadata, and Molty labels from docs/docs.json.
• Allows the Molty auth URL and copied transcript assistant name to be configured by downstream docs builds.
• Improves URL rewriting so downstream docs can keep app-root links outside the docs base path while resolving docs-relative Markdown and repo-relative source links correctly.

Proof

npm run docs:build && npm run docs:smoke

Relevant output:

rendered 509/509 per-page og cards
built 23016 pages in dist/docs-site (full)
docs search index ok: 683 entries
Indexed 11831 pages
docs site smoke ok: shell, routing, skin, and hidden fixture checks passed (full)

Review Notes

• This preserves OpenClaw defaults when config fields are absent.
• This is the companion PR for the ClawHub /docs adapter PR, which consumes the shared builder instead of vendoring it.
