CPU Light Load 1.0.5 - Source Preview

Initial public source release of CPU Light Load, an independent PowerToys Command Palette extension. Includes adjustable low-priority CPU work, timed and unlimited runs, optional sign-in startup, safety watchdogs, documentation, and an MIT license. The clean source builds successfully and all 73 local regression checks pass, including the one-minute heartbeat test. This is source-only: no signed installer or binary download is provided. A GitHub Actions workflow is included as an optional template; hosted CI is not enabled or verified. See README.md and docs/BUILDING.md for developer build and installation instructions.
