Initial commit: DeathWatch, an Elden Ring death counter for OBS

Reads the game's process memory read-only (AOB signature scanning,
re-resolved every tick — never a cached pointer) and serves a live
death counter as a browser-source overlay plus a status panel.

Supports co-op: each player runs the program locally, one acts as
hub. The peer link is authenticated (HMAC challenge/response, no
token on the wire, constant-time compare) but not yet encrypted —
see CLAUDE.md's TODO section for the planned TLS+pinning split.

Zero external dependencies — including a hand-rolled WebSocket
implementation — so the whole thing ships as one .exe.
