feat: auto-learning — detect repeated patterns and generate rules automatically #816
Description
Purpose
Detect repeated patterns across sessions (same errors, same fixes, same feedback) and automatically suggest or create rules. Turn tribal knowledge into codified rules without manual effort.
Changes
- Pattern detection engine (analyze execution history for repetitions)
- Rule suggestion: "You've fixed this import pattern 3 times — create a rule?"
- Auto-generate rule draft in .ai-rules/rules/
- Feedback loop: user approves/rejects suggested rules
Acceptance Criteria
- Detects repeated error→fix patterns across 3+ sessions
- Suggests new rule with evidence (which sessions triggered it)
- Generates rule draft following codingbuddy pattern
- User approval required before rule is active
- Depends on cross-session history (#C)
