fix: resume generation from quality v2 records

[wenn-id]

Summary

• read generation dependencies from schema 2.0 panel QA bindings
• preserve schema 1.0 compatibility
• keep existing generation cache reusable when evidence migrates without dependency changes

Root cause

The panel validator accepted schema 2.0 records, but resume-plan still read only schema 1.0 top-level fields. Valid migrated records therefore produced stage inputs are unavailable: ValueError and incorrectly requested panel regeneration.

Verification

• RED reproduced the exact regenerate / ValueError failure
• focused regression passes
• resume suite: 48 passed
• full suite: 344 passed, 1 skipped
• real Batch A probe changes generation from incorrect regenerate to reuse
• distribution + clean-install contracts pass
• wheel clean-install base and MCP smokes pass

Summary by CodeRabbit

• Bug Fixes
  • Improved resume support for both current and legacy panel QA records.
  • Preserved generation-stage cache reuse when resuming from current-format records.
  • Continued enforcing panel matching and dependency validation.

📝 Walkthrough

Walkthrough

The resume flow now parses schema 2.0 panel QA records alongside legacy records. It validates panel IDs and reuses generation-stage cache entries when prompt and reference bindings match.

Changes

Resume Schema Support

Layer / File(s)	Summary
QA dependency parsing scripts/comic_sol.py, tests/test_resume.py	Schema 2.0 records use subject_id and bindings. Legacy records retain their existing fields. Tests verify generation-stage cache reuse across both schemas.
