When running in --auto or headless mode, the discuss step could loop
indefinitely — each pass reads its own CONTEXT.md, finds "gaps" in
referenced types/interfaces, creates new decisions to fill them, and
repeats. Observed: 34 passes, 167 decisions, 7 hours, zero code written.
Fixes:
- Add max_discuss_passes config (default: 3) to WorkflowConfig
- Add single-pass guard instruction to SDK self-discuss prompt
- Add pass cap documentation to CLI discuss-phase workflow
- Add pass guard step to SDK headless discuss-phase prompt
- Add stall detection note to autonomous workflow
