📄 Description

what

split the gated 5-widget check-2 cell in vol1/lab_00_introduction.py into:

ungated widget-defs cell (always defines model_size, quantization, move_server, faster_gpu, edge_deploy)
gated display cell (renders them conditionally on check1 being answered)

this matches the canonical pattern from lab_01 post-#1339 and keeps downstream helpers (check2empty, check2value_list at line 1372) from hitting undefined widgets when check1 has not been answered.

also removed the _KNOWN_MULTI_LEAK_LABS grandfather set in labs/tests/test_static.py now that it is empty. the one-widget-per-gated-cell rule applies strictly to all 33 labs going forward.

why manual

lab_00 uses check1/check2/check3 sequential concept checks, structurally different from the partX_prediction idiom elsewhere. the mechanical Pattern C transform from #1352 would have broken test_engine because check2 helpers rely on all 5 checkboxes being globally defined.

test plan

labs/tests/test_static.py passes (no more skip for lab_00, 792 passed 4 skipped 1 xfailed)
labs/tests/test_engine.py passes (app.run headlessly)
python3 -m marimo check vol1/lab_00_introduction.py clean (exit 0)
CI green on dev

closes #1347
