Every thread (agent turns + terminal + project commands) now execs into one
persistent per-user container (spoon-box-{username}) instead of ephemeral
docker run --rm — so the agent and terminal share the exact same running
environment, filesystem, and in-session installs.
- docker.ts: ensureUserContainer (persistent box) + streamExecInContainer/
runExecInContainer (docker exec, streaming) sharing a factored streamSubprocess
- user-container.ts: reference-counted box lifecycle (held while any thread
workspace is active or a terminal is connected; idle-reaped after
SPOON_AGENT_BOX_IDLE_MS, default 30m)
- worker.ts: runClaim acquires the box; codex turn + runProjectCommand exec into
it; release on stop/PR/failure
- terminal.ts: execs into the shared box (dockerode TTY) instead of a per-job
container; materializeUserHome runs the dotfiles setup in the box
- Verified: agent + terminal run in the same box, share fs, dotfiles + tmux load
