Extract a RAII RenderEndpoint that owns the enumerator/endpoint/client/
render-event/buffer for both AudioMirror::run_hooked and run_loopback,
replacing two hand-rolled setup+teardown blocks and their two identical
fail lambdas with one set_error helper; every COM object now frees on
each exit path automatically.
Route audio_format_verifier's mono decode through the shared
correlate_detail::decode_layout instead of a second copy, and read the
debug env var via GetEnvironmentVariableA (drops the getenv C4996).
Fold the near-identical read_frame/read_pixel staging-copy setup in
SharedTextureSource into one map_staging_copy, and the three separate
case-insensitive filter helpers (log/injection panels) into
ui/text_match.hpp.
Comments: drop game-name anecdotes and "the old code"/version phrasing;
genericize the override-file example; fix a stale heartbeat-interval
note. Behavior unchanged (host tests + mock_game_test pass).
Persist audio overrides keyed by game image name (coop_audio_overrides.ini
next to the exe) so a known-bad game is auto-corrected on its next launch:
on attach to a guessed stream the host applies any saved override, and a
manual Override now saves too. A format the hook catches exactly at
IAudioClient::Initialize is auto-saved as that game's override (ground truth);
if it overwrites a differing stored value, a warning is logged. Host-originated
log lines now reach the Log window via IpcServer::host_log (color-coded).
Validated live (harness): a pre-seeded override for coop_tone is auto-applied
over the guess (state -> manual override, 48000/2/16). audio_overrides_test
covers persist/reload/case-insensitive lookup/differing-overwrite. Trim README.
