/**
 * Per-project AI dev container ("vibn-dev").
 *
 * One Coolify Service per Vibn project, running the `vibn-dev` image.
 * The AI agent drives it via:
 *   - shell.exec   → docker exec into the container (via existing SSH path)
 *   - fs.*         → file ops (implemented as `cat` / `tee` / `rm` etc.
 *                    inside the container, on top of shell.exec)
 *   - dev_server.* → start long-running processes (week 2)
 *   - ship         → git push to Gitea + trigger Coolify deploy (week 2)
 *
 * Lifecycle states:
 *   - Not provisioned   → ensureDevContainer() creates the Coolify service
 *   - Suspended         → Coolify-stopped (saves money). resume() starts it.
 *   - Running           → docker exec works.
 *
 * Tenant safety: every helper takes a workspace and the caller must have
 * already verified that the projectId belongs to that workspace via
 * fs_projects. The exec primitive ALSO verifies the resolved container
 * UUID is in the workspace's owned Coolify-project set, so a hijacked
 * projectId can't reach unrelated containers.
 *
 * See: AI_PATH_B_EXECUTION_PLAN.md §3.
