feat(navi): structured geocode with usaddress parsing and reranker

Browse source 
Add lib/geocode.py — multi-source retrieval pipeline:
- usaddress CRF parsing with intent classification
- Netsyms structured lookup (uses raw street abbreviations)
- Photon /structured + /api freetext retrieval
- Weighted 10-signal reranker (housenumber, street fuzz, locality,
  source authority, etc.)
- match_code annotations + address book proximity labeling
- Trace log at /tmp/geocode_rerank_trace.log

nav_tools.py now delegates geocode() to the new module.
Tests updated: US address queries correctly return Netsyms results.
