(Migrated from github.com)

Cherry-picked off diag/session-config-logging with all diagnostic-only logging commits stripped:

connect: map Steam external id → peer's real Epic handle in EpicAccountId_FromString — the load-bearing fix (UE friend-search is epic-keyed)
presence: auto-derive local presence from a presence-enabled lobby (+ release announce-hold, real product identity, MAX_PRESENCE_RECORDS 8→24)
social: map Steam external accounts to PUIDs over the LAN beacon
auth: EpicAccountId_FromString returns NULL for malformed ids (crash-fix)
lobby_search / session_search owner-match; immediate session propagation

Builds clean on CI (verified the bridge + presence-from-lobby symbols are present in the artifact).

Mainline the generic LAN-emu fixes that enable native friends-list browse→join for EOSPlus+Steam titles (validated end-to-end on StarRupture: friend appears in Join Game → join → `Welcomed by server` → travel into host world).
