fix: plan generation API no longer cancels prematurely
The plan generation API (/api/generate-plan-detailed) was incorrectly
detecting client disconnection because it listened to req.raw.on('close')
which fires when the HTTP request body finishes parsing, not when the
actual TCP connection closes.
This caused the error "Failed to parse plan - no JSON array found" because
the server would cancel all subagent sessions almost immediately after
starting them.
Fix:
- Changed from req.raw.on('close') to socket.on('close')
- Added responseSent flag to only cancel if response hasn't been sent
- Added E2E test to verify the fix
Tested with:
- Simple plan generation: 61 items, 138.5s, quality 0.82
- Smartphone app plan: 53 items, 93.4s, quality 0.75
