`desktop_apps` could omit a running app when Ace trimmed a large inventory, leaving agents no way to find it. Add an optional case-insensitive name/bundle-ID query, applied to the full native result before the existing text limit. Filter scope and matching/total counts remain distinct from native completeness and response truncation.

Closes #83. Part of #8 and #5. The native client and global payload cap are unchanged.

Validation: type checks, formatting/lint, Ace diff review, and independent source review passed. A real read-only smoke used this exact host adapter with the existing signed native runtime: the unfiltered list reproduced 107 returned/42 omitted and missed Ace; trimmed case-insensitive name and bundle-ID searches found the exact PID/generation, a nonmatch returned zero, invalid queries were rejected, and all replies stayed within 32 KB. Native completeness and target metadata were retained. No model run or new native build was needed for this host/channel/docs change.

### Built in Ace

Used Ace's terminal for dependencies, checks, Git, and GitHub, and its changes/patch surface to review the three-file diff. Codex source tools performed editing and independent review because external agent/editor integration remains tracked in #9 and #22. The reported truncation was observed through Ace's real host adapter and signed native bridge.
