conductor(plan): mark sub-track 2A (pydantic in models.py) complete [01ddf9f1]

Resuming sub-track 2 (audit violations) per user direction. Sub-track 2A cleared 1 of 61 violations (pydantic in src/models.py via PEP 562 __getattr__ + pydantic.create_model). 60 remain across file_cache (4), api_hooks (4), sloppy (5), app_controller (23), gui_2 (24). Next: 2B (tree_sitter in file_cache.py).

    *Goal: Reduce sloppy.py startup time. Main Thread Purity Invariant. 9 phases, 57 tasks. 44 TDD tests added (all passing). 7 main thread purity tests enforce invariant for 6 refactored files.*
    *Final measured: import src.ai_client 161ms (was 1800ms; 91% reduction / 1638ms saved). import src.gui_2 341ms (was 1770ms; 81% reduction / 1429ms saved). Total ~3067ms saved on the 2 big files. 62 audit violations remain (was 63 after Sub-track 2 partial; was 67 baseline) - all 6 refactored files contribute 0 new violations.*
