feat: convert all pipeline.py commands to Go

Complete conversion of pipeline.py into Go `lem` CLI:
- import-all: bulk import all LEM data into DuckDB from M3
- consolidate: pull worker JSONLs, merge, deduplicate
- normalize: seeds → deduplicated expansion_prompts table
- approve: filter scored expansions → training JSONL
- tier-score: heuristic/judge tiered expansion scoring
- expand-status: expansion pipeline progress from DuckDB
- inventory: DuckDB table counts and summary
- coverage: seed coverage gap analysis
- seed-influx: bootstrap InfluxDB from DuckDB golden_gen
- query: ad-hoc SQL against DuckDB

22 commands total, 49 Go files. Replaces entire pipeline.py.
