- Add .tmp directory to .gitignore to exclude temporary files from version control
- Add force-gpu-mem-available-mb=512 to cap compositor tile memory budget - Add gpu-rasterization-msaa-sample-count=0 to disable MSAA - Add unit tests for both flags in environment.test.ts Closes #4365

Changes
electron/setup/environment.ts— two newapp.commandLine.appendSwitchcalls for GPU memory constraintselectron/setup/__tests__/environment.test.ts— new test file with coverage for all GPU memory flagsTesting
Unit tests added and passing. Flags are safe at 512 MB (well above the ~384 MB threshold where WebGL would fall back to software rasterization). Relates to the broader memory reduction initiative in #4141.
