2ed9335f4e feat(geocode): add viewport bias for location-aware search 
- Add lat/lon/zoom params to geocode() and _retrieve_photon_freetext()
- Update nav_tools.py wrapper to pass through viewport params
- Add /api/geocode handler support for lat/lon/zoom query params
- Add _safe_float() helper for param validation
- Cast zoom to int for Photon compatibility

Allows the frontend to pass current map center/zoom to bias
search results toward the visible area.

ac69e2761d feat(navi): add /api/reverse endpoint for map-click reverse geocoding 
Accepts lat/lon query params, calls Photon /reverse, returns same
response shape as /api/geocode. Returns 200 with empty results on
no match (graceful degradation for ocean/unmapped areas).

c76d63b785 refactor(navi): Photon-first geocoding with ranked results 
Inverts the /api/geocode chain. Photon is now the primary search
engine; the hand-rolled Netsyms free-text parser is removed.
Address book short-circuits nicknames only ("home", "work") —
full-address queries flow through Photon and address book
entries within 75m annotate matching results with labeled_as.
Coordinate strings detected before search.

Response shape: /api/geocode now returns a ranked candidates
list (always 200 OK, empty list if no match). No more 404 for
unmatched queries. Users can type messy input — wrong case,
missing punctuation, abbreviations, typos — and get results
or close matches.

Netsyms preserved at /api/netsyms/lookup for direct access.
USPS plus4 enrichment of Photon street-address hits is a
planned follow-up.

dfab388769 feat(navi): add netsyms tier-2 geocoding + geocode API 
Add Netsyms AddressDatabase2025 (159M US+CA addresses) as tier-2
in the geocode chain: address_book → netsyms → photon.

- lib/netsyms.py: SQLite lookup module (lazy, read-only, thread-safe)
- lib/netsyms_api.py: Flask blueprints for /api/netsyms/* and /api/geocode
- lib/netsyms_test.py: 7 test cases (street, free-text, zipcode, health)
- lib/nav_tools.py: new geocode() with consistent {name,lat,lon,source,raw}
- lib/api.py: register netsyms_bp and geocode_bp
