The spec described invariant reconciliation as happening 'during Strategize'
only. The implementation (PR #5614) runs reconciliation at all three phase
transitions: Strategize, Execute, and Apply.
Added §Reconciliation Failure Behavior documenting:
- Reconciliation runs at start_strategize(), execute_plan(), apply_plan()
- ReconciliationBlockedError is raised when reconciliation fails
- INVARIANT_VIOLATED event is emitted on the event bus
- Resolution path: plan correct + retry
- Post-correction reconciliation via CORRECTION_APPLIED event subscription
- Built-in actor: builtin/invariant-reconciliation
Closes#5942
