Jason dc52dfcb47 test(mechanics): PR-I.2 — tb_system_mechanics for chirp/RF/safety/CDC ...

New TB carving G1 (reset & init), G2 (TX chain — minus G2.2 which lives
in dataflow), G3 (safety architecture), G7.1 (rapid chirp toggle CDC),
and G7.3 (TX chirp counter CDC) out of tb_system_e2e into a fast,
focused subsuite. radar_system_top instantiated with USB_MODE=1
(production FT2232H path).

These tests don't need 48-chirp Doppler accumulation, so the sim
budget is ~80 us of stimulus + observation. Watchdog at 1.5 ms.

15/15 PASS. Pairs with tb_system_opcodes (commit 413a01e) to cover
~half of what tb_system_e2e exercised; the heavy data-flow / reset-
recovery groups (G2.2, G4, G5, G8, G9) move to tb_system_dataflow
in PR-I.3.
