chore: remove unused SupervisedProc.launchJob base method

[detail-app]

Description

Removes the base SupervisedProc.launchJob method, which was fully superseded by the override in JobProcExecutor and never executed in production.

Changes Made

• Removed the launchJob(info: RunningJobInfo) method from SupervisedProc in agents/src/ipc/supervised_proc.ts.

Pre-Review Checklist

• Build passes: All builds (lint, typecheck, tests) pass locally
• AI-generated code reviewed: Removed unnecessary comments and ensured code quality
• Changes explained: All changes are properly documented and justified above
• Scope appropriate: All changes relate to the PR title, or explanations provided for why they're included
• Video demo: A small video demo showing changes works as expected and did not break any existing functionality using Agent Playground (if applicable)

Testing

• Automated tests added/updated (if applicable)
• All tests pass
• Make sure both restaurant_agent.ts and realtime_agent.ts work properly (for major changes)

Additional Notes

The base launchJob was dead since inception: JobProcExecutor overrides it without calling super, and InferenceProcExecutor (which inherits it) never has launchJob invoked — it implements InferenceExecutor, not JobExecutor. The only call-site (proc_pool.ts:94) dispatches via JobProcExecutor's override, never the base. Leaving it was also misleading since the base checks proc?.connected while the real implementation checks init.done and sets #jobStatus.

History

• Last materially changed January 2026 (fix(agents): prevent crash when child process dies #935 @Hormold)
