feat: UI parser kinds, nodeSelector textarea, step-limit session clear, per-line path redaction

- ui-parser: add thinking kind + handler for standalone thinking events, thinking
  blocks in assistant content arrays, and user-turn tool_result blocks
- job-manifest: parseKeyValueOrObject helper so nodeSelector (and labels) accept
  key=value textarea lines in addition to JSON objects
- parse: isOpenCodeStepLimitResult detects step_finish with max_turns / max_steps /
  step_limit reason
- execute: return clearSession:true when step limit reached so next run starts fresh;
  redactHomePathUserSegments moved to per-line to prevent paths split across chunks
- tests: ui-parser.test.ts (new), extended parse.test.ts and job-manifest.test.ts
