Add Mission Control integration with per-project toggle

When enabled, the entrypoint clones mission-control into ~/mission-control
(persisted on the home volume) and symlinks it to /workspace/mission-control.
Flight Control global and project instructions are programmatically appended
to CLAUDE.md. Container recreation is triggered on toggle change.
