feat(build): ENV-first Deno + discovery metadata (os/arch/github ref) + Xcode Cloud
- env.go (new): DENO_ENABLE and DENO_BUILD environment variables activate
Deno builds even when repo only has package.json or bare frontend/ dir
- wails.go + node.go + apple.go + release.yml + xcode_cloud.go: honor the
ENV flags across builder + workflow + Xcode Cloud script generation
- discovery.go: record host os/arch + GitHub ref metadata (ref, branch, tag,
is_tag, sha, short_sha, repo, owner)
- api/provider.go: /discover exposes the new metadata
- Regression coverage across discovery/builders/apple/workflow/xcode_cloud/api
Verified: go test ./... passes
