Local search comparison

[plural]

Add a tool to compare local SQLite search results with the API server. This will help us debug local search and ensure that the server and browser versions have identical behavior.

Run this with npm run compare-search -- --limit 10000 --parallel 50 and adjust flags as needed.

Example output (final bit):

Comparison complete: 5768 passed, 287 failed, 816 both failed.
API caching stats: 6055 total requests, 5997 cache hits, 58 cache misses (issued).
