fix(webicached): conf-driven variant exclusion; fix sttr darwin universal

- TagVariants now applies confVariants from releases.conf as case-folded
  substring matches before package-specific logic, removing the need to
  hardcode simple variant names in Go
- gitea: variants = gogit (excludes Windows gogit builds)
- lsd: variants = msvc (moved from Go to conf)
- pwsh: variants = fxdependent fxdependentWinDesktop appimage
- bun: variants = profile (moved from Go to conf)
- sttr: darwin_all tagged as universal2 so arm64 and amd64 Mac users
  are served; pkg.tar.zst excluded (Arch Linux package format)
- add .claude/ to .gitignore
