Two bugs:
1. _parse_classify_output stripped <think> block before searching for JSON.
DeepSeek-R1 often puts the JSON array inside the think block (especially
when it "decides" mid-reasoning), so stripping it first destroyed the data.
Fix: search full output first, then inside <think>, then stripped — three
fallback strategies with info logging at each step.
2. Phase 2 save used bare UPDATE WHERE domain=? which silently does nothing
if the domain row doesn't exist yet in enriched_domains.
Fix: replace with INSERT ... ON CONFLICT DO UPDATE (true upsert).
Also adds logger.info lines so container logs show raw DeepSeek output
and parse result count for easy debugging.
