Mark Henderson d6c87a052e feat(domains): P5.1 — OpenSRS registration + Cloud DNS + Coolify attach ...

Adds end-to-end custom apex domain support: workspace-scoped
registration via OpenSRS (Tucows), authoritative DNS via Google
Cloud DNS, and one-call attach that wires registrar nameservers,
DNS records, and Coolify app routing in a single transactional
flow.

Schema (additive, idempotent — run /api/admin/migrate after deploy)
  - vibn_workspaces.dns_provider TEXT DEFAULT 'cloud_dns'
      Per-workspace DNS backend choice. Future: 'cira_dzone' for
      strict CA-only residency on .ca.
  - vibn_domains
      One row per registered/intended apex. Tracks status
      (pending|active|failed|expired), registrar order id, encrypted
      registrar manage-user creds (AES-256-GCM, VIBN_SECRETS_KEY),
      period, dates, dns_provider/zone_id/nameservers, and a
      created_by audit field.
  - vibn_domain_events
      Append-only lifecycle audit (register.attempt/success/fail,
      attach.success, ns.update, lock.toggle, etc).
  - vibn_billing_ledger
      Workspace-scoped money ledger (CAD by default) with
      ref_type/ref_id back to the originating row.

OpenSRS XML client (lib/opensrs.ts)
  - Mode-gated host/key (OPENSRS_MODE=test → horizon sandbox,
    rejectUnauthorized:false; live → rr-n1-tor, strict TLS).
  - MD5 double-hash signature.
  - Pure Node https module (no undici dep).
  - Verbs: lookupDomain, getDomainPrice, checkDomain, registerDomain,
    updateDomainNameservers, setDomainLock, getResellerBalance.
  - TLD policy: minPeriodFor() bumps .ai to 2y; CPR/legalType
    plumbed through for .ca; registrations default to UNLOCKED so
    immediate NS updates succeed without a lock toggle.

DNS provider abstraction (lib/dns/{provider,cloud-dns}.ts)
  - DnsProvider interface (createZone/getZone/setRecords/deleteZone)
    so the workspace residency knob can swap backends later.
  - cloudDnsProvider implementation against Google Cloud DNS using
    the existing vibn-workspace-provisioner SA (roles/dns.admin).
  - Idempotent zone creation, additions+deletions diff for rrsets.

Shared GCP auth (lib/gcp-auth.ts)
  - Single getGcpAccessToken() helper used by Cloud DNS today and
    future GCP integrations. Prefers GOOGLE_SERVICE_ACCOUNT_KEY_B64,
    falls back to ADC.

Workspace-scoped helpers (lib/domains.ts)
  - listDomainsForWorkspace, getDomainForWorkspace, createDomainIntent,
    markDomainRegistered, markDomainFailed, markDomainAttached,
    recordDomainEvent, recordLedgerEntry.

Attach orchestrator (lib/domain-attach.ts)
  Single function attachDomain() reused by REST + MCP. For one
  apex it:
    1. Resolves target → Coolify app uuid OR raw IP OR CNAME.
    2. Ensures Cloud DNS managed zone exists.
    3. Writes A / CNAME records (apex + requested subdomains).
    4. Updates registrar nameservers, with auto unlock-retry-relock
       fallback for TLDs that reject NS changes while locked.
    5. PATCHes the Coolify application's domain list so Traefik
       routes the new hostname.
    6. Persists dns_provider/zone_id/nameservers and emits an
       attach.success domain_event.
  AttachError carries a stable .tag + http status so the caller
  can map registrar/dns/coolify failures cleanly.

REST endpoints
  - POST   /api/workspaces/[slug]/domains/search
  - GET    /api/workspaces/[slug]/domains
  - POST   /api/workspaces/[slug]/domains
  - GET    /api/workspaces/[slug]/domains/[domain]
  - POST   /api/workspaces/[slug]/domains/[domain]/attach
  All routes go through requireWorkspacePrincipal (session OR
  Authorization: Bearer vibn_sk_...). Register is idempotent:
  re-issuing for an existing intent re-attempts at OpenSRS without
  duplicating the row or charging twice.

MCP bridge (app/api/mcp/route.ts → version 2.2.0)
  Adds five tools backed by the same library code:
    - domains.search    (batch availability + pricing)
    - domains.list      (workspace-owned)
    - domains.get       (single + recent events)
    - domains.register  (idempotent OpenSRS register)
    - domains.attach    (full Cloud DNS + registrar + Coolify)

Sandbox smoke tests (scripts/smoke-opensrs-*.ts)
  Standalone Node scripts validating each new opensrs.ts call against
  horizon.opensrs.net: balance + lookup + check, TLD policy
  (.ca/.ai/.io/.com), full register flow, NS update with systemdns
  nameservers, and the lock/unlock toggle that backs the attach
  fallback path.

Post-deploy checklist
  1. POST https://vibnai.com/api/admin/migrate
       -H "x-admin-secret: $ADMIN_MIGRATE_SECRET"
  2. Set OPENSRS_* env vars on the vibn-frontend Coolify app
     (RESELLER_USERNAME, API_KEY_LIVE, API_KEY_TEST, HOST_LIVE,
     HOST_TEST, PORT, MODE). Without them, only domains.list/get
     work; search/register/attach return 500.
  3. GCP_PROJECT_ID is read from env or defaults to master-ai-484822.
  4. Live attach end-to-end against a real apex is queued as a
     follow-up — sandbox path is fully proven.

Not in this commit (deliberate)
  - The 100+ unrelated in-flight files (mvp-setup wizard, justine
    homepage rework, BuildLivePlanPanel, etc) — kept local to keep
    blast radius minimal.
