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.

+**Accepted 2026-11-13 (#829, #853 closed).** The owner accepted the driver because the hardware evidence did not
+change its code. That evidence is the 2026-11-11 iTNC 530 run (`evidence/heidenhain-live-2026-11-11.md`) plus the
+ignitionoee CR capture of 2026-11-13 (`6d2aec40`, `docs/recipes/evidence/heidenhain-runstate-sample-2026-11-13/`): a
+7 h read-only sample of 34 production controls on the Java LSV2 driver this one was ported from. It showed
+`ProgramState` 0 coinciding with axis motion in 11,865 of 11,869 sample pairs and 7 = idle. TNC 426/430 (NC 280476)
+answered `BadNotSupported` for status, program, axes and alarms. Overrides were `BadUserAccessDenied` under INSPECT,
+capabilities read `Unknown` until their first poll, and comms loss recovered on reconnect. Alarm classes 1/7/8 were
+seen; class 5 was not. The items below remain known limits, not acceptance blockers.

+No real control was available for this port at first. Still open:
