Propagate manager crashes from PgQueuer.run() so failures are no longer silently swallowed.

Full changelog

Bug Fixes

  • Propagate manager crashes from PgQueuer.run() instead of silently swallowing them (#553) - Previously, if either the QueueManager or SchedulerManager crashed during PgQueuer.run(), the exception was silently absorbed by the TaskManager wrapper and the process would hang or exit without any indication of failure. Now, PgQueuer.run() uses asyncio.gather directly so that a crash in either manager immediately propagates the exception to the caller, cancels the sibling task, and sets the shutdown event. This makes failures visible and allows proper error handling by callers.

Improvements

  • Simplify PsycopgDriver notification listener (#551)
  • Use AsyncRawCursor and dict_row in PsycopgDriver for cleaner internals (#547)
  • Remove redundant dict() wrappers in model_validate calls (#552)

Documentation

  • Add CLAUDE.md with project conventions and architecture guide (#557)
  • Overhaul documentation with a real landing page and structured navigation (#544)

Chores

  • Slim CI matrix from 44 to 22 jobs, capping at 20 concurrent (#549)
  • Improve docker-compose readability (#546)
  • Standardize commit conventions in AGENTS.md (#548)
