Third of four stacked PRs for Slice 1. The task service API contract (contracts #3 and #4).

  • TaskService — deterministic orchestration; transition enforcement via the engine; liveness registrations.
  • FastAPI REST API — repos, tasks, transitions, slug, artifacts, liveness (register/heartbeat/deregister), discovery; domain errors → HTTP codes.
  • Artifact store (interface + filesystem adapter + id→path→MCP-URI resolver, ADR 0003).
  • MCP surface contract defined (server wired in Slice 2).

Stacked; base is slice1/02-persistence. Adds fastapi/uvicorn/httpx.

feat(taskservice): REST API, liveness protocol, artifact store, MCP c…
de83f4e 
…ontract

Slice 1, PR 3 of 4 — the task service API contract.

- panopticon.taskservice.service.TaskService: deterministic orchestration over the
  repository — tasks, transition enforcement (via the engine), slug, artifacts, and
  ephemeral liveness registrations. Injectable clock + id factory for test determinism.
- panopticon.taskservice.api: FastAPI app factory exposing repos, tasks, transitions
  (with per-responsibility settlement on the wire), slug, artifacts, liveness, and
  discovery, with domain exceptions mapped to HTTP status codes.
- panopticon.core.artifacts + taskservice.artifacts_fs: the artifact-store interface, the
  filesystem adapter, and the shared id->path->MCP-URI resolver (ADR 0003).
- panopticon.taskservice.mcp: the MCP surface contract (resource URI scheme + tool
  specs), defined now; the server is wired when real containers connect (Slice 2).

Adds fastapi + uvicorn (runtime) and httpx (dev, for TestClient).
