Zac Gaetano 53c06a9af9 feat(ui): single-instance enforcement via per-user named mutex 
Two simultaneous TeamsISO processes contend over the NDI runtime, the same default sender names, and %APPDATA%\\TeamsISO\\config.json — observed during testing when launchers / shortcuts produced duplicate windows. Add a Local namespace per-user-keyed mutex (Local\\WildDragon.TeamsISO.SingleInstance.<username>) at startup; if a second instance can't claim it, broadcast a registered window message ('WildDragon.TeamsISO.BringToFront') and Shutdown(0). The running instance subscribes to that message via ComponentDispatcher.ThreadFilterMessage and surfaces its main window when received.

Per-user keying lets two different Windows users on the same machine each run their own TeamsISO. Mutex is released and disposed on OnExit.

Verified: Start-Process the exe twice in a row -> only one process remains, with the original window surfaced.

TeamsISO

Per-Participant NDI ISO Controller for Microsoft Teams.

TeamsISO sits between Microsoft Teams' raw NDI broadcast output and a live-production environment. It receives each participant's NDI stream, normalizes framerate and resolution per a configured target, and re-emits clean, individually-addressable NDI sources for ingestion into a switcher (vMix, OBS, Ross, hardware capture).

Status

Pre-1.0. See docs/superpowers/specs/ for the active spec and docs/superpowers/plans/ for in-flight implementation plans.

Build

Requires .NET 8 SDK.

dotnet build
dotnet test
