refactor: unify server lifecycle, migrate gRPC client, and clean up sandbox v2

Server lifecycle:
- Introduce service.Service to manage HTTP + gRPC startup/shutdown
- Fix gRPC mutex deadlock in StartServer when port is occupied
- Add GracefulStop with 5s timeout before forced Stop in grpc.go
- Pre-check HTTP and gRPC port availability in cmd/start.go
- Print gRPC server address in startup access-points block

gRPC client refactor:
- Move token manager and client from tai/grpc/ to grpc/client/
- Add backward-compatible aliases in tai/yao.go and tai/token.go
- Update cmd/run.go to import grpc/client directly (no tai dependency)

Sandbox v2 docker migration:
- Delete sandbox/v2/docker/ (moved to tai repo)
- Update sandbox/docker/build.sh hint to point to tai repo
- Clean up .gitignore entries for removed docker directory
- Temporarily disable SandboxV2Test and BenchmarkSandboxV2 in CI
  (docker images need rebuild after tai repo migration)

Tai integration:
- Add direct-mode registration API handlers in tai/api/
- Add heartbeat handler and token management wrappers
- Update tai/registry and tai/tunnel for latest protocol
- Replace yao-grpc references with tai call in docs

 Tai gateway currently dials a fixed `YaoUpstream` at startup. New behavior: yao-grpc tells Tai where to forward via request metadata (`x-grpc-upstream`). Tai reads the target address and proxies to it — removes `YaoUpstream` startup config.

 General-purpose gRPC gateway exposed by the Yao process. Not limited to sandbox IPC — it exposes process execution, shell, API proxy, MCP, LLM, and Agent capabilities to any gRPC client. 14 RPCs defined; V1 (unary + LLM/Agent streaming) complete, V2 (base streaming via `gou/stream`) pending.
 
 **Clients:**
-- Container-internal `yao-grpc` (via Tai Gateway relay or direct)
+- Container-internal `tai call` (via Tai Gateway relay or direct)
 - `yao run` CLI (after `yao login`)
 - Other Yao instances (future node-to-node)
 
 **IPC path (replacing Unix socket):**
 ```
-Local:   Container → yao-grpc (tai/grpc/) → Yao gRPC 127.0.0.1:9099
+Local:   Container → tai call (tai repo) → Yao gRPC 127.0.0.1:9099
-Remote:  Container → yao-grpc (tai/grpc/) → Tai Gateway (:9100 gRPC) → Yao gRPC Server (:9099)
+Remote:  Container → tai call (tai repo) → Tai Gateway (:9100 gRPC) → Yao gRPC Server (:9099)
 ```
 
 All modes use gRPC — no Unix socket fallback. `yao-grpc` reads `YAO_GRPC_ADDR` from env and connects. Local containers point directly at the Yao gRPC server on loopback; remote containers point at the Tai relay. Tai does **not** know Yao gRPC address at startup — `yao-grpc` carries target in `x-grpc-upstream` request metadata. This keeps Tai stateless and allows one Tai to serve multiple Yao instances.
