feat: Ralph Loop integration — mini-reflect, alternatives, structured confidence

- Mini-Reflect for fast workflow: Creator must restate task, list assumptions,
  name highest-damage risk before proposing (catches misunderstandings early)
- Alternatives Considered section: Creator must evaluate 2+ approaches with
  rejection rationale before committing to one (prevents tunnel vision)
- Structured confidence scoring: 3-axis table (task understanding, solution
  completeness, risk coverage) replaces bare 0.0-1.0 number. Low scores
  trigger targeted action (clarify, upgrade workflow, or research)
- Mini-Reflect fallback for skipped tasks: quick reflection even when
  ArcheFlow doesn't activate (non-trivial single-file changes)

+**Mini-Reflect fallback:** Even when skipping ArcheFlow, apply a quick reflection for non-trivial single-file changes: (1) restate what you're changing, (2) name one assumption, (3) check if it could break anything. This takes ~10 seconds and catches misunderstandings before they become commits.
