The Windows build never actually used ccache; the '.ccache' directory only ever held the win_flex_bison install, and cmake/MSVC did no compiler caching. Clean this up: - Drop the CCACHE_* environment variables from the job (meaningless here). - Store win_flex_bison in a dedicated 'win_flex_bison' directory instead of the misleadingly named '.ccache', and cache just that (static key, as it is a fixed third-party tool). - Set WIN_FLEX_BISON inside ci-win-compile.ps1 as an absolute path, rather than in the workflow, making the script self-contained. - Use the runner's processor count for build parallelism instead of a fixed '-j 3', in both ci-win-compile.ps1 and ci-win-test.ps1. - Remove the verilator-win.zip archive and upload steps; nothing consumes that artifact. - Build Verilator with the Ninja generator from an MSVC developer shell instead of MSBuild. MSBuild only parallelizes across projects, and Verilator is a single project, so it compiled serially; Ninja keeps all cores busy. Also compile with /Od: this job only checks that Verilator builds and can verilate an example, so an optimized binary is not needed and the otherwise-dominant optimizer time is wasted.
