feat(T2.4): implement fast lessons file indexing
- Add internal/indexing package for lessons index - Implement LessonIndex with multi-field index structure - Index by task type, activity type, failure type, and pattern - Fast lookups: O(1) map access for all query types - Build from JSONL file with streaming parse - Support incremental lesson addition - Query operations with optional AND logic - Time range queries for temporal analysis - Similarity search by failure message substring - Most frequent failures ranking - 20 indexing tests, all passing Features: - FindByTaskType() - query by task type - FindByActivityType() - query by activity type - FindByFailureType() - query by failure type - FindByPattern() - query by pattern - FindSimilar() - substring search in failure messages - QueryMultiple() - AND logic for multi-field queries - GetByTimeRange() - temporal range queries - GetMostFrequentFailures() - ranked by frequency - BuildFromFile() - load from JSONL - AddLesson() - incremental updates Performance Verified: - Lookup < 10ms for 1000s entries ✓ - <10ms for 10,000 entries ✓ - Concurrent queries supported ✓ - O(1) average lookup complexity - Index rebuilding efficient Test Coverage: - 20 indexing tests (build, query, range, stats) - Latency verification (< 10ms) - Concurrency testing - Time range queries - Multi-field queries - Large dataset support (10k entries) Index Structures: - lessons: ID -> Lesson (full lookup) - byTaskType: TaskType -> []*Lesson - byActivityType: ActivityType -> []*Lesson - byFailureType: FailureType -> []*Lesson - byPattern: Pattern -> []*Lesson - All RWMutex-protected for thread safety Next: T2.5 (Git operation batching)
