- Create Dockerfile.base with all tools and dependencies (built once)
- Slim down Dockerfile to just copy scripts from base image
- CI checks for base image existence, builds if missing
- Runtime builds drop from ~17min to ~10sec (only copies scripts)
- Base image only needs rebuild when tools/versions change
Add tmux to the claude-dev runtime contract so persistent terminal sessions can rely on it, and make the Claude preflight patch resilient to current CLI builds so image builds keep passing.

Switch claude-dev to node:20-bookworm-slim and preload the base image from server2 in CI to avoid slow pulls on the NAS runner.

Define claude-dev capabilities as a tested contract and deploy immutable tags only after smoke checks so daily tooling upgrades remain CI-first and rollback-safe.
