refactor(monorepo): extract inbox and orch runtimes

docs/implementation-roadmap.md

@@ -39,6 +39,7 @@ As of now:
 - a repository-level skill workspace monorepo migration plan now exists under `docs/skill-workspace-monorepo.md`, defining the target split between runtime packages under `packages/`, agent-facing skill bundles under `skills/`, support apps under `apps/`, and package-based skill packaging flows
 - the first migration phase for the skill workspace monorepo is now complete: root `go.work` exists, `pnpm-workspace.yaml` now discovers `packages/*`, empty runtime module roots now exist under `packages/`, and a declarative `scripts/skill-bundles.json` plus `scripts/package_skill_runtimes.sh` scaffold now define package-oriented skill bundle metadata from the repo root
 - `packages/coord-core` now exists as the first real extracted runtime package, containing shared coordination DB/schema, protocol, and store code, and the active coordination runtimes now import `coord-core` instead of root `internal/db`, `internal/store`, and `internal/protocol`
+- `packages/inbox-runtime` and `packages/orch-runtime` now exist as package-owned runtimes with their own `cmd/` entrypoints and package-local CLI wiring/tests, and the root skill packaging flow now builds `skills/inbox`, `skills/orch`, and `skills/council-review` from package entrypoints instead of root `cmd/` paths
 - a repo-local `scripts/package_skill_clis.sh` packaging flow now builds bundled skill CLI assets for `inbox`, `orch`, and `council-review`
 - `orch` now implements `run init/show`, `task add`, `dep add`, `ready`, `dispatch`, `reconcile`, `wait`, `blocked`, `answer`, `retry`, `reassign`, `cancel`, `cleanup`, and `status`
 - `orch` can create runs, gate tasks through dependencies, dispatch work through `inbox`, reconcile worker thread state back into task state, answer blocked tasks, retry or reassign work, cancel tasks or runs, clean attempt worktrees, and create per-attempt Git worktrees during strict dispatch

 6. import `repo-memory` only after the package-based runtime and skill packaging pattern exists
 
-The inbox implementation and its human-readable test-plan set are already in place, `orch` supports the main scheduler loop plus the complete council start/wait/tally/report workflow, the web product now has its first real operator-facing read surfaces, and the repository has completed both the workspace bootstrap and the shared coordination-kernel extraction phases of the skill monorepo migration, so the next step should be runtime extraction rather than continuing to accrete new root-owned runtimes.
