fix(desktop): ship the VC++ runtime the Windows voice wheels need

onnxruntime (wake word) and ctranslate2 (local speech-to-text) link against
msvcp140.dll and msvcp140_1.dll, which the managed CPython does not ship.
On Windows without the system VC++ Redistributable both imports failed with
"DLL load failed: The specified module could not be found", so "Hey Hermes"
and voice chat transcription never worked.

- Bundle the Microsoft-signed VC143 CRT set (14.44.35211, matching the
  managed CPython's vcruntime140) as a Windows extra resource with a SHA-256
  manifest.
- Before every local backend start, copy missing or mismatching CRT files
  beside the managed python.exe (the process image directory, searched first),
  verifying digests; never overwrite the interpreter's own vcruntime and never
  block boot. Existing installs heal on their next launch.
- Report an unloadable native voice wheel as a VC++ runtime problem in the
  wake-word requirements, local transcription and `hermes doctor`, instead of
  treating installed package metadata as proof the wheel loads.
- Bump AITURK IDE to 1.0.0-beta.12.
