Hardening: schedule consistency, Redis atomicity/perf, and timeout correctness

Highlights

• Improved schedule upsert consistency across adapters.
• Fixed worker timeout edge cases and timeout listener cleanup.
• Optimized Redis schedule listing and made schedule deletion atomic.
• Expanded integration test coverage for Redis and Knex behavior.
• Reduced internal any usage and tightened TypeScript types.

What’s Changed

• Fixed Redis schedule upsert to clear stale scheduling fields.
• Renamed schedule creation flow to upsertSchedule, kept createSchedule as deprecated wrapper.
• Fixed schedule manual trigger queue routing and queue manager re-init behavior via follow-up fixes.
• Fixed worker timeout listener cleanup to prevent retained abort listeners.
• Fixed timeout: 0 handling so it behaves as an immediate timeout.
• Preserved runCount on schedule upsert for adapter parity.
• Moved queue-isolation assertions from fake-adapter-only tests to shared adapter contract tests.
• Optimized Redis listSchedules with pipelining (removes N+1 request pattern).
• Made Redis deleteSchedule atomic using MULTI/EXEC.
• Added Redis integration test helper for write-stream spying.
• Added Knex query-spy helper and query-count tests for listSchedules and deleteSchedule (SQLite + PostgreSQL).
• Refactored internal typing to reduce any usage and improve dispatcher/worker type safety.
• Added repository GitHub link in package.json.
• Dependency update and general maintenance changes.
