Move inline/lazy imports to top-level now that blake3 is a main dependency and
circular-import concerns are resolved. Remove decorative section-header comments
in asset_reference queries. Allow the seed API endpoint to temporarily re-enable
the seeder when --disable-assets-autoscan is active so manual triggers still work.
Add retry-on-409 logic in test helpers and remove try/finally around prompt
execution in favour of sequential pause/resume.

- Make blake3 import lazy in hashing.py (only imported when needed)
- Add compute_hashes parameter to AssetSeeder.start(), build_asset_specs(), and seed_assets()
- Fix missing tag clearing: include is_missing states in sync when update_missing_tags=True
- Clear is_missing flag on cache states when files are restored with matching mtime/size
- Fix validation error serialization in routes.py (use json.loads(ve.json()))

Make blake3 an optional import that fails gracefully at import time,
with a clear error message when hashing functions are actually called.
