fix: GoReleaser build from CLI entry point instead of GUI

- Changed main path from ./main.go (Wails GUI) to ./cmd/dev-cleaner/main.go (CLI)
- This fixes v1.0.1 release which had no binaries due to build failure
- GUI entry point requires CGO and Wails build, not compatible with GoReleaser
- Future: Will create separate workflow for GUI releases
