Steam: the lobby + IDENTITY-TOKEN roster -- internet MP code-complete (step 4c)

Browse Source 
NEW gated (BT_STEAM) game/glass/btl4lobby: an ISteamMatchmaking room replacing
the arcade Site-Management screen -- host creates (lobby data btl4=1), members
join by filter, pilots publish name/mech/color, the host ENTER mints the
roster and signals GO.

THE FAKEIP LESSON (live-verified, prior-art assumption DISPROVEN): a fresh
process gets a DIFFERENT FakeIP, so menu-time fake addresses go stale by
mission time -- the first cycle timed out connecting to its own stale address.
Redesign: roster addresses are opaque ipv4-shaped TOKENS (169.254.77.N with
ports 1501/1502) minted by the host at GO, mapped to Steam IDENTITIES;
connections ride ConnectP2P(identity, channel) with console=0/game=1 virtual
ports; the map reaches mission processes via env (BT_FE_MYFAKE +
BT_FE_STEAMMAP); the GetMyAddress seam feeds the pod its own token for roster
self-match; CheckSocket reports peers by token.  L4STEAMNET reworked (no
FakeIP allocation at all); the marshal gained the Steam-wire branch.

Verified single-machine (ON/ON, live Steam): menu -> HOST STEAM LOBBY ->
room -> GO -> token map minted -> egg roster carries the token -> mission
process up with 1 roster token incl. self -> pod self-matches -> stock
console ladder -> mission RUNS (46 ticks).  Remaining: the live 2-account
cross-machine session (docs/STEAM_TEST.md).
