feat: Implement async import jobs with background worker#295
Merged
Conversation
This fixes fedify-dev#94 where importing follows would block the server. Changes: - Add database tables for import jobs and items with status tracking - Create background worker that polls for pending jobs every 5 seconds - Process imports in batches with concurrency control (batch 10, concurrent 5) - Add progress tracking UI with auto-refresh - Support job cancellation for in-progress imports - Graceful shutdown handling for the import worker 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
Use FOR UPDATE SKIP LOCKED to ensure multiple worker instances don't process the same import job or items concurrently. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Replace raw SQL `ANY(${itemIds})` with Drizzle's `inArray()` function.
The raw SQL was incorrectly generating `ANY(($3, $4, ...))` which
PostgreSQL rejects as invalid syntax (error 42809). The `inArray()`
function properly generates an `IN` clause.
