The follow-up backlog had drifted into three settled peer/runtime issues: the legacy game-list fallback contradicted the one-wire-version policy, the Tauri shell still re-derived local install state from disk after peer snapshots, and `Availability::Downloading` existed even though active operations are already reported through a separate operation table. Remove the legacy `AnnounceGames` request and fallback service. Discovery now ignores peers that do not advertise the current protocol and a peer id, and library changes are sent through the current delta path only. This keeps the runtime aligned with the documented current-build-only interoperability model. Make peer `LocalGamesUpdated` snapshots authoritative for local fields in the Tauri database. The GUI-side catalog still owns static metadata such as names, sizes, and descriptions, but downloaded, installed, local version, and availability now come from the peer runtime instead of a second whole-library filesystem scan. Snapshot reconciliation also pins the missing-begin and missing-finish lifecycle cases in tests. Collapse availability back to the settled `Ready` and `LocalOnly` states. Aggregation now counts only `Ready` peers as download sources, and the frontend no longer carries a dead `Downloading` enum value. The core peer also exposes the small non-GUI hooks needed by scripted callers: startup options for state and mDNS, a local-ready event, direct connection, peer snapshots, and an explicit post-download install policy. Those hooks reuse the same current protocol path and do not add compatibility shims. Test Plan: - `git diff --check` - `just fmt` - `just clippy` - `just test` Refs: BACKLOG.md, FINDINGS.md, IMPL_DECISIONS.md

Description
Peer-to-peer game library sharing for LAN parties.
- Peers let users browse and download games from each other
- they discover each other on the local network via mDNS
- they exchange library metadata over QUIC
Ships as a Tauri desktop app.
