[ZJLi2013]

Keeps only the objects that the four scenarios load, plus the scene base assets:

• Kept: apple_01, die_01, lego_02, mug_02, plane, table_simple; assets/articraft/ unchanged.
• Removed: apple_02, block_blue, carton_01, carton_02, fruit_03, and their catalog.json entries.
• Tests that seeded the library with block_blue now use die_01; the name-derived grasp category test uses apple_01.
• Default asset lists in validate_asset_picks.py and run_metadata_guided_rollout.py now name only assets that exist.

Asset management gets its own rework later; this keeps the library at the minimum the demos need.

Test: pytest tests — 135 passed, 1 skipped.
