Implement hook step-based concurrency system
This implements the hook concurrency plan from TODO_hook_concurrency.md:
## Schema Changes
- Add Snapshot.current_step (IntegerField 0-9, default=0)
- Create migration 0034_snapshot_current_step.py
- Fix uuid_compat imports in migrations 0032 and 0003
## Core Logic
- Add extract_step(hook_name) utility - extracts step from __XX_ pattern
- Add is_background_hook(hook_name) utility - checks for .bg. suffix
- Update Snapshot.create_pending_archiveresults() to create one AR per hook
- Update ArchiveResult.run() to handle hook_name field
- Add Snapshot.advance_step_if_ready() method for step advancement
- Integrate with SnapshotMachine.is_finished() to call advance_step_if_ready()
## Worker Coordination
- Update ArchiveResultWorker.get_queue() for step-based filtering
- ARs are only claimable when their step <= snapshot.current_step
## Hook Renumbering
- Step 5 (DOM extraction): singlefile→50, screenshot→51, pdf→52, dom→53,
title→54, readability→55, headers→55, mercury→56, htmltotext→57
- Step 6 (post-DOM): wget→61, git→62, media→63.bg, gallerydl→64.bg,
forumdl→65.bg, papersdl→66.bg
- Step 7 (URL extraction): parse_* hooks moved to 70-75
Background hooks (.bg suffix) don't block step advancement, enabling
long-running downloads to continue while other hooks proceed.
