The CSpeedTreeRT stand-in now returns the collision objects stored in
the .spt (12000 section: spheres and cylinders) instead of one fixed trunk
cylinder, and takes leaf texture rects from the 10000 section instead of
hand-picked atlas rects (trees without leaf maps use the frond rect).
SpeedGrass/BoundaryShapeManager are N_A (no 40250 caller).

Copy SoundBase/SoundData/SoundInstance*/SoundManager*/Type from 40250 and
implement the AIL_* calls they make in MilesAil.cpp (2D pan, 3D distance and
listener pan, threaded stream decode, loop counts). The SDL host drains the
mixer. CSoundManager is created/updated/destroyed where 40250 does it and the
old AudioCommands bridge is removed. Port-map MilesLib 142/142 PORTED.

Replace the macOS-only AudioToolbox decoder with mt_host::decode_audio: a
RIFF/WAVE PCM parser plus vendored dr_mp3, resampled/remixed to 44.1 kHz
stereo float with SDL_ConvertAudioSamples. macOS and Android now share one
path; the AudioToolbox link is gone.
BGM is no longer cached in clips_ (a 5-minute track is ~100 MB of float):
only the playing track is kept, and a new one decodes on a worker thread
(the pack read stays on the main thread) so map changes do not stall.
host.audio_decode test: synthetic wav layouts + all 1578 pack .wav, 9 pack
.mp3 and 25 Client/BGM .mp3 decode (7060 s of audio in ~3.6 s on M2).
