feat(cdn-reads): Phase 5 — CDN-first bundle reads via Cloudflare

Bundle GET presigned URLs are now rewritten through the CDN base URL when BLOB_STORAGE_CDN_BASE_URL is set, so repeat clones hit the Cloudflare edge cache instead of R2/MinIO directly.

- Add blob_storage_cdn_base_url setting to config - presign_bundle_get rewrites host to CDN base URL (scheme+netloc swap, path preserved); regular object presign_get is unaffected - put_bundle writes Cache-Control: public, max-age=31536000, immutable so Cloudflare caches content-addressed bundles indefinitely at edge - CDN-1..5 TDD tests all green (23/23 across phases 1-5)
