- Debug command now orchestrates: gather symptoms in main context, spawn
investigation subagent with fresh 200k context
- Subagent template unified for both /gsd:debug (find_and_fix) and
diagnose-issues (find_root_cause_only) flows via goal flag
- Checkpoint behavior enables subagent to pause for user input
(human-verify, human-action, decision) with continuation agents
- Structured return formats: ROOT CAUSE FOUND, DEBUG COMPLETE,
INVESTIGATION INCONCLUSIVE, CHECKPOINT REACHED
- diagnose-issues updated to match new template placeholders and returns
