Replace the per-group agent-runner-src copy model with a single shared
read-only mount. Source and skills are now RO + shared; personality,
config, working files, and Claude state stay RW + per-group.
Key changes:
- Mount container/agent-runner/src/ RO at /app/src (all groups share one copy)
- Mount container/skills/ RO at /app/skills; per-group skill selection via
symlinks in .claude-shared/skills/ based on container.json "skills" field
- Mount container.json as nested RO bind on top of RW group dir
- Move all NANOCLAW_* env vars to container.json (runner reads at startup)
- New runner config.ts module replaces process.env reads
- Move command gate (filtered/admin) from container to host router
- Dockerfile: remove source COPY, split CLI installs (claude-code last),
move agent-runner deps above CLIs for better layer caching
- Add writeOutboundDirect for router denial responses
- Design doc at docs/shared-src.md
Not included (follow-up): DB migration to drop agent_provider columns,
cleanup of orphaned agent-runner-src directories.
