Oban Pro 1.7.0 ships database-backed workflow tracking, replaces the
generated `uniq_key` / `partition_key` columns with expression
indexes, and adds new partial indexes for query performance.
Switches oban_pro from the vendor/ tree to the licensed `oban` hex
repo (auth already configured via `mix hex.repo`). vendor/oban_pro
deleted — the vendoring was a 1.6.x stopgap, 1.7 is the first
version we land directly from hex.
oban_met (1.1.0) and oban_web (2.12.1) stay vendored — they're
not published to the licensed `oban` repo (verified by 404 on
`mix hex.package fetch`).
Migration 20260430142341 runs `Oban.Pro.Migration.up(version: "1.7.0")`
which creates the workflow tables and the new indexes. Verified on
dev + test DBs. Production is well below the size threshold the v1.7
guide flags for split-migration handling, so the inline default
suffices.
No code changes for the breaking-change list — the codebase only
references Oban.Pro.Engines.Smart and Oban.Pro.Plugins.DynamicLifeline,
both unchanged in 1.7. We don't use Workflow.after_cancelled/2 or
Oban.Pro.Workers.Chunk.
Test suite stays at 3132/3132.
