0.7.6:0 — bundle Station Master v0.7.6

Submodule pinned to v0.7.6 (b4f09f0). current.ts bumped in place at
0.7.6:0 — no new version file, no migration: fixes a client-side
routing bug in the solitaire door that v0.7.5 introduced (a browser
that had ever held a multiplayer seat could not reach the new setup
screen at all), so every game in progress carries over without
exception.

Verified: npm run check clean, prettier clean, make x86 packs as
v0.7.6:0, installed on phoenix.local — logs show the empty migration
running and both games in progress (WHISTLE-4086, COAL-7370) resuming
with their same intent counts, and the served index.html confirmed to
link the solitaire door to ./play.html?solitaire.

 **What changed in 0.7.5.** Solitaire now asks before it deals. A genuinely fresh visit to the
 solitaire page opens a setup screen with the full set of options — game type, starting hand, where
 an Extra may start, the revenue rates, victory conditions, and the optional rules — the same
