v0.14.3-heap-poisson.1-rc-pyroscope

fix: correct two-layer upscale weight for heap sampling

The live-objects profiler had a ~10x undercount because GetUpscaleWeight()
only compensated for our secondary Poisson filter (layer 2) while ignoring
the CLR's own size-proportional AllocationTick sampling (layer 1).

Fix the two bugs together:
- ShouldSample() now decrements by the 100KB AllocationTick window instead
  of objectSize, so the filter operates on the same unit the CLR uses.
- GetUpscaleWeight() now computes w_clr × w_ours: the CLR layer weight
  (allocationWindow/objectSize ≈ 100) times the our-filter layer weight
  (samplingRate/allocationWindow ≈ 5.5), giving a combined ≈550 instead
  of the broken ≈512.

v0.14.0-rc.7-pyroscope

Fix pthread_sigmask wrapper: use sigismember loop instead of memcmp

memcmp fails due to uninitialized padding bytes in sigset_t structure.
Instead, iterate through signals to check if SIGSEGV is the only signal
in the set before adding SIGPROF.
