enricobuehlerandClaude Fable 5 789dafc95f feat(capture/windows): the stall micro-probes get an off switch, the depth pin a backoff ...

Two standing costs from the interval-stutter investigation, consolidated:

- PUNKTFUNK_STALL_PROBES=0 now opts a box out of the micro-probe engine
  (per-GPU 10 Hz fence copies, a parked blocking-DwmFlush waiter, the
  5 ms-cadence CPU sentinel). Default stays ON while the field program
  runs; off, stall lines keep the driver telemetry and the cheap ETW
  present/queue discriminator and only lose the corroborating probe legs
  — the verdict matrix already treats an absent probe window honestly.

- The negotiated-depth pin-back stops hammering a display that refuses
  the flip: it was 4 CCD writes + 8 display-config queries per second,
  forever, all on the session-global display-config lock. After ~2 s of
  eager retries it re-attempts every ~4 s — still self-healing, without
  the drumbeat.
