v0.3.0: CI dotnet 8.0.424 pinned with isolated install

- Pin .NET SDK to 8.0.424 in all CI jobs to avoid floating channel drift

- Install SDK to runner temp via DOTNET_INSTALL_DIR to bypass

  C:\\Program Files\\dotnet overwrite/extract conflicts on Gitea Windows runners

- Simplify release job to dotnet publish + upload-artifact

- Exclude memory-bank/ via .gitignore (internal dev memory stays local)
