feat(fast-deploy): target the live deployment id for content-push sync

[hugo-ccabral]

What

Content is now keyed per deployment in KV (decofile:<id>). A content-only fast-deploy must write to whichever version is currently live, so the tanstack-kv reconciler resolves the site's index:live pointer (Cloudflare KV REST GET) before creating the sync Job and passes it as DEPLOYMENT_ID.

Behavior

• New cfkv.go: fetchKVLiveID reads index:live for the site's namespace.
• Reconciler: resolve live id → pass DEPLOYMENT_ID=<liveId> to the Job (syncer runs deco-sync-blocks-to-kv --deployment-id "$DEPLOYMENT_ID").
• index:live unset (no code deploy yet) → Synced=Unknown / reason Waiting + requeue; no Job created.
• Live-id resolver is injectable → unit-testable without HTTP.
• No CR schema change — the live id is resolved at reconcile time (the existing Spec.DeploymentId is the unrelated ConfigMap/Knative pod-label field).

Depends on

• decofile-syncer image passing --deployment-id (infra PR).
• @decocms/start per-deployment keying (blocks PR). Inert until a site has deployed once and set index:live.

Test

go build / go test ./internal/deploy/... / go vet pass. 3 new tests: buildJob env carries DEPLOYMENT_ID; Waiting-when-pointer-absent; Job targets the live id.

Summary by cubic

Fast-deploy now writes content to the currently live deployment by resolving index:live in Cloudflare KV and passing that id to the sync Job. This aligns content pushes with the live site and avoids updating the wrong version.

• New Features

  • Reconciler reads index:live via Cloudflare REST using the operator’s CF creds and passes it to the Job as DEPLOYMENT_ID (syncer runs with --deployment-id).
  • When index:live is unset, mark Synced=Unknown with reason Waiting, requeue, and skip Job creation.
  • Added internal/deploy/cfkv.go and an injectable live-id resolver; tests cover waiting behavior, Job env, and targeting the live id.
  • Docs updated for per-deployment keys and the monorepo rename (@decocms/tanstack, @decocms/blocks, @decocms/blocks-cli), including build/deploy commands to seed and flip index:live, and how to verify DEPLOYMENT_ID.

• Dependencies

  • decofile-syncer must support --deployment-id.
  • Runtime uses @decocms/tanstack with per-deployment keying; CLI is @decocms/blocks-cli. A site must have set index:live via a prior code deploy.
