- The macOS SIGSEGV moved from the gl_bridge unit tests (already gated)
to other real-GL users in the same binary (suites::gl_render,
render_driver): make the gate systemic in the test build on macOS.
gl_available() reports unavailable and acquire() fails unless
OAK_GPU_TESTS is set, so every unit test takes its documented CPU
fallback; release builds are untouched.
- Dump Apple's crash reports on macOS failure: a SIGSEGV in a test binary
prints nothing, and the .ips report carries the native stack.
- The Windows-only multicam graph test failure now prints both decoded
media probes and both rendered source pixels: that separates a broken
test-media encode from a broken graph switch in one run.
