Every Faust render, and every trial-loop lane, runs dotnet with a fresh
DOTNET_CLI_HOME under the temp directory. The SDK's first-run experience
appends "<home>\.dotnet\tools" to the persisted user PATH each time, and
DOTNET_SKIP_FIRST_TIME_EXPERIENCE does not stop that part. Seventy-nine
dead entries had accumulated (9,634 chars), past cmd's environment limit,
so anything spawned through cmd lost the tail of PATH — node included.
DOTNET_ADD_GLOBAL_TOOLS_TO_PATH=0 is the switch that governs the PATH
write. Set it everywhere a throwaway dotnet home is used; telemetry
opt-out rides along for the renderer since these homes never persist.
