ALC_MAJOR/MINOR_VERSION only report the OpenAL API spec level (always 1.1),
which is misleading. Additionally log alGetString(AL_VERSION) (e.g.
"1.1 ALSOFT 1.24.2") once a context is current, and relabel the spec line.
OpenAL does not re-route on its own, so unplugging the active output device
(e.g. headphones) mid-game left the sim silent until restart. Poll ALC_CONNECTED
(ALC_EXT_disconnect) at ~1 Hz and, when the device is lost, reopen playback on
the current default output via alcReopenDeviceSOFT, preserving the context and
all sources. Tokens are declared locally since the bundled AL headers ship no
alext.h; the entry point is resolved at runtime, so this is a no-op (with a log
warning) on OpenAL Soft builds too old to provide ALC_SOFT_reopen_device.
Enabling GLM_FORCE_DEFAULT_ALIGNED_GENTYPES makes glm::vec3 16 bytes (padded),
but the listener orientation was passed to alListenerfv as
reinterpret_cast<ALfloat const *>(glm::vec3[2]). With the padding the six
floats OpenAL reads are at.x, at.y, at.z, PAD, up.x, up.y - the 'up' vector is
taken from padding garbage, corrupting the listener basis (right = at x up) and
swapping left/right of every positional sound.
Build the 6 floats explicitly instead of reinterpreting a padded vec3 array.
