Changes since v0.5.4

MaskEvents undercount in STR.edf — MaskEvents was set to the number of
on/off pairs instead of the total number of on+off events. OSCAR divides
MaskEvents by 2 to get the pair count, so the reported session count was
half of what it should have been.
(main/edf_gen.c)
Repeating -120 L/min flow spikes in OSCAR/SleepHQ — BLE notification
drops (typically every ~10 minutes) triggered insertion of SNT_MISSING
(INT16_MIN) sentinels into BRP flow/pressure data. During EDF conversion
these were clamped to dig_min = -1000, which OSCAR scales by gain = 0.12
(L/s→L/min), producing visible -120 L/min spikes. Changed BRP gap
compensation to hold-previous-value (matching the existing SA2/PLD
strategy). Gaps are typically 200–400 ms (<10 % of a breath cycle), so the
held value is visually indistinguishable from real data. The AS11 native EDF
never has missing BRP data, and OSCAR has no sentinel convention for
breathing waveforms.
