fix(acp-bridge,openclaw): use AgentRelay.spawnAgent instead of removed spawnPty

[willwashburn]

Summary

Fixes the failing CI build on main (run 26520261748).

After PR #1003 / #1006, AgentRelay only exposes spawnAgent — spawnPty lives only on AgentRelayClient. Two callers were still using relay.spawnPty(...) on AgentRelay instances, which broke the TypeScript build of @agent-relay/acp-bridge (the visible CI failure) and would have broken @agent-relay/openclaw next.

• packages/acp-bridge/src/acp-agent.ts:739 — relay.spawnPty(...) → relay.spawnAgent(...)
• packages/openclaw/src/spawn/process.ts:174 — same

Test plan

• npm run build is green locally (all 19 turbo tasks)
• CI on this PR passes

📝 Walkthrough

Walkthrough

This PR switches two relay SDK spawn call sites from spawnPty to spawnAgent. In acp-bridge and openclaw/spawn, agent relay invocations now use spawnAgent with the same name, CLI, task, and configuration arguments, while maintaining existing readiness waits and error handling flows.

Changes

Spawn Method Migration

Layer / File(s)	Summary
Spawn API migration across packages packages/acp-bridge/src/acp-agent.ts, packages/openclaw/src/spawn/process.ts	Both handleSpawnCommand and ProcessSpawnProvider.spawn switch from relay.spawnPty(...) to relay.spawnAgent(...) while preserving identical arguments and surrounding spawn configuration logic.

Possibly related issues

• AgentWorkforce/relay#998: These changes align with the goal of adding and surfacing additional spawn methods on AgentRelay (spawnHeadless/spawnProvider/spawnAgent).

Possibly related PRs

• AgentWorkforce/relay#846: Both PRs touch the CLI "spawn" command path and relay spawn invocation; the retrieved PR updates spawn mocks and scoping around the spawn call, while this PR switches the relay method being invoked.

Poem

🐰 A spawn call hops from pty to agent bright,
Two pathways sync with method new in sight,
No args confused, same config stays the same,
The relay dances to a different name! 🎭
