simulation: don't start worker HTTP server

[rosetta-livekit-bot]

Summary

• add a simulation mode flag to worker options
• skip worker HTTP server creation/start/close while running CLI simulations
• add a patch changeset

Testing

• pnpm build:agents
• pnpm format:check
• pnpm --filter @livekit/agents lint (passes with existing warnings)

Notes

• pnpm api:check currently fails outside this change because plugin API checks can run before plugin dist declarations exist; agents-only API check also fails on the existing API Extractor export * as ___ limitation in generated dist declarations.

Original PR description

Summary

Running two lk agent simulate sessions concurrently fails with "address already in use": each launched worker bound the health/debug HTTP server on the same fixed port.

Under --simulation the worker is ephemeral and CLI-supervised — nothing scrapes its health endpoint — so the server is now simply not created. http_port registration and shutdown already handled the None case.
