Add docs/contributing/activation_trace.md: a 210-line contributor guide covering the env-gated activation trace infrastructure (Extension 0), its five configuration env vars, the trace_step() context manager, and the JSONL output format. The doc also sketches Extensions 1-3 (FX graph capture, AST-level instrumentation, dispatch-table interception) as future work, giving contributors a clear design ladder to climb without requiring them to implement everything at once. Update tests/local_tests/magi-human.md with the Wave 9 investigation entry: records the E2E smoke result (28,864 JSONL records, 451 hooked modules), the zero-overhead-when-off confirmation, and the new fastvideo/tests/hooks/test_activation_trace.py test row in the Phase 11 status table. Last-verified date bumped to 2026-05-01 (Wave 9).
