fix: Replace Chocolatey with direct download for Windows capnproto setup (#12222) ## Summary - Replaces `choco install capnproto` with a direct download from `capnproto.org`, eliminating flaky 503 errors from Chocolatey's community API - Adds `actions/cache` for the Windows capnproto binary (matching the existing Linux caching pattern), so ephemeral/bare runners only download once per cache key ### Testing The "Setup capnproto" step on Windows CI jobs should now reliably succeed regardless of Chocolatey's availability. On cache hit, the download is skipped entirely.
