refactor(issue): simplify Issue schema and remove lifecycle_requirements

Schema changes:
- Remove lifecycle_requirements (deferred to plan agent)
- Remove solution_count (computed dynamically from solutions/*.jsonl)
- Keep context as single source of truth (remove problem_statement)
- Add feedback[] for failure history + human clarifications
- Add source, source_url, labels, expected/actual_behavior

Fields removed (unused downstream):
- lifecycle_requirements.test_strategy
- lifecycle_requirements.regression_scope
- lifecycle_requirements.acceptance_type
- lifecycle_requirements.commit_strategy
- solution_count (denormalized)

Fields added:
- feedback[]: { type, stage, content, created_at }
- source, source_url, labels
- expected_behavior, actual_behavior, affected_components
