feat(standards): serve service version-wiring rule + bundle wiki pages in MCP

Versioning standard now states services must read their VERSION (e.g. a build arg) rather than hardcoding it; the compliance prompt repeats it. build_bundle also bundles src/wiki/** as wiki_-prefixed modules (e.g. docs://modules/wiki_development_releasing), so the release runbook is reachable from the MCP. Bundle grows to 22 modules.
