Changelog

POST /v1/enrollments/{id}/run-now. Sets next_run_at = now() on an active enrollment so the next 60-second tick picks it up immediately.

GET /v1/flows/{id}/node-counts. Returns a map of node-id → currently-paused-on count.

Editing send_window_* / send_days_of_week / timezone on a flow now walks active and paused enrollments and pulls next_run_at backwards only — never into the past.

Native flows engine: /v1/flows, /v1/enrollments, /v1/flow-runs. Replaces the dormant Apollo-sequence flow.

Three new node types: update_stage, add_to_pool, goal.

apollo_email_accounts and the per-user pointer. Apollo is data-only; sends route through Gmail.

linkedin to the touchpoint_channel enum.
