feat: containerized execution with agent tooling and deployment fixes

- ContainerRunner replaces ClaudeRunner/GeminiRunner; all agent types run
  in Docker containers via claudomator-agent:latest
- Writable agentHome staging dir (/home/agent) satisfies home-dir
  requirements for both claude and gemini CLIs without exposing host creds
- Copy .credentials.json and .claude.json into staging dir at run time;
  GEMINI_API_KEY passed via env file
- Fix git clone: remove MkdirTemp-created dir before cloning (git rejects
  pre-existing dirs even when empty)
- Replace localhost with host.docker.internal in APIURL so container can
  reach host API; add --add-host=host.docker.internal:host-gateway
- Run container as --user=$(uid):$(gid) so host-owned workspace files are
  readable; chmod workspace 0755 and instructions file 0644 after clone
- Pre-create .gemini/ in staging dir to avoid atomic-rename ENOENT on first
  gemini-cli run
- Add ct CLI tool to container image: pre-built Bash wrapper for
  Claudomator API (ct task submit/create/run/wait/status/list)
- Document ct tool in CLAUDE.md agent instructions section
- Add drain-failed-tasks script: retries failed tasks on a 5-minute interval
- Update Dockerfile: Node 22 via NodeSource, Go 1.24, gemini-cli,
  git safe.directory=*, default ~/.claude.json
