-- AI Ticket Analyzer — link-aware bundle support.
-- See docs/wulf-pulse-ticket-analyzer-build-notes.md (Phase 3).
--
-- A "bundle" is an aggregate report that was triggered from a single ticket
-- analysis page (typically a master/problem ticket) and is waiting for the
-- per-ticket analyses of its referenced tickets to complete before it can run.
--
-- Adds:
--   1. expected_ticket_numbers TEXT[]   — the full set the bundle is waiting on
--   2. triggered_by_ticket_number TEXT  — the master ticket the user clicked from
--   3. New status value 'pending_analyses' — set while underlying analyses are
--      still running. Worker chain-trigger flips it to 'pending' once all
--      expected tickets have a complete analysis, then runAggregateReport runs.
