-- AI Ticket Analyzer — provider column for per-run LLM provider tracking.
--
-- Adds a `provider` field so multiple analyses can coexist for the same
-- ticket from different LLM providers (Claude vs DeepSeek-via-OpenRouter)
-- without colliding on the (ticket_number, analysis_version) uniqueness.
--
-- analysis_version is now monotonic *within (ticket_number, provider)*, not
-- globally per ticket. This means:
-- - The first Anthropic run is v1, first OpenRouter run is also v1.
-- - Re-runs of Anthropic produce v2, v3, …; OpenRouter likewise.
