Archive deepen-connected-services + sync spec deltas

Task 7.3: applies the MODIFIED + ADDED requirements from
changes/deepen-connected-services/specs/ into openspec/specs/:

- connected-services/spec.md:
  - MODIFIED: OAuth token storage (renamed sync_connections → connected_services
    with credential_kind discriminator + JSONB credentials shape).
  - ADDED: Capability seams for providers (Importer / RoutePusher /
    WebhookReceiver per ADR-0002, no unified SyncProvider).
  - ADDED: Centralized credential lifecycle via ConnectedServiceManager.

- wahoo-import/spec.md: Provider-agnostic framework rewritten to reference
  capability seams + per-provider manifest. Token refresh now goes through
  withFreshCredentials. Renames sync_connections → connected_services
  throughout.

- wahoo-route-push/spec.md: Renames sync_connections → connected_services.
  ADDED: RoutePusher capability seam — shape (service, route) →
  {remoteId, version} per ADR-0003; Wahoo workarounds stay inside the
  adapter.

Change directory moved to openspec/changes/archive/2026-05-08-deepen-connected-services/.
