Vijay Janapa Reddi 3a555deabd feat(labs): rebuild all 32 labs with chapter-grounded parts, ed-tech review fixes, and test infrastructure
Complete lab curriculum rebuild:
- 16 Vol1 + 16 Vol2 labs (33,368 lines across 32 files)
- Each lab has 4-5 pedagogically grounded parts + synthesis
- Parts proposed by agents reading actual chapter QMD files
- Ed-tech review identified and fixed: redundancies, time overruns, mlsysim gaps
- V2-03 + V2-06 merged into "Communication at Scale"
- 17 old/superseded files deleted (pre-merger, pre-renumber)

Structural fixes applied:
- V1-01 Part C replaced (Silent Decay -> Triad Across Targets)
- V1-03 grounded in mlsysim (Engine.solve for OOM, Engine.sweep for configs)
- V1-09 Part C replaced (Curriculum Learning -> Preprocessing Tax)
- V1-13 Part E dropped (redundant with Lab 10)
- V1-15 Part C dropped (TCO not fairness-specific), refocused
- V2-12 model extraction dropped, restructured around privacy cost
- V2-16 capstone cut to 4 parts, Design Ledger fallbacks added
- All 15-min parts trimmed to 12 min

Test infrastructure added:
- labs/tests/ with 3-level pytest suite (static, engine, widget)
- CI workflow updated with pytest stages
- pytest added to labs/requirements.txt
