docs(heidenhain): driver accepted, #829/#853 closed

The ignitionoee CR capture (6d2aec40: 7 h read-only sample of 34 production
controls on the Java LSV2 driver) and the 2026-11-11 iTNC 530 run did not
change the driver's code: ProgramState 0 = cutting (11,865 of 11,869 motion
pairs), 7 = idle; TNC 426/430 BadNotSupported; overrides BadUserAccessDenied
under INSPECT; capabilities Unknown until first poll; alarm classes 1/7/8 seen,
class 5 not. Owner accepted the driver on that basis; remaining limits stay
documented in Heidenhain.md §Hardware-gated.
