perf(android): filter class pages before bridge serialization (#4791)

Browse Source 
Filter class names at the native owner before serialization, and resume matching pages through contiguous inventory positions without a second index or query-result cache. Preserve selected source Evidence, query identity, complete top-level coverage and shared CLI/MCP behavior.

Fixes #4776.
