skill_install fails on Windows because _skillInstaller.prepareSkillDirectory is not a function

[KMX415]

Summary

Trying to install the regular YOLO 2026 skill (yolo-detection-2026) on a Windows RTX host fails immediately with:

_skillInstaller.prepareSkillDirectory is not a function
This happens before any YOLO-specific setup starts, so it looks like a bug in the generic skill installer/runtime rather than the skill itself.

Environment

OS: Windows (win32 x64)
Host:
Node: v24.11.1
GPU: RTX
Skill: yolo-detection-2026 (regular, not Coral)
Steps to reproduce

Start/restart the app/backend
Attempt to install yolo-detection-2026
Observe immediate failure:
_skillInstaller.prepareSkillDirectory is not a function
Expected

Installer prepares the skill directory and continues setup
Actual

Install aborts immediately with the error above
Notes

Reboot/restart did not fix it
Likely causes:
backend/installer version mismatch
stale build artifacts
import/export or module resolution issue
regression in installer API
Suggested checks

Log the runtime shape/keys of _skillInstaller
Verify prepareSkillDirectory exists in the loaded installer implementation
Clean/rebuild and confirm no stale installer module is being loaded

@KMX415 , Thanks for providing valuable feedback, we've fixed the bugs but since we enabled may cloud APIs and 10k-20k code base change, so we are testing still. If you want, please check out the latest version ( not yet rolling out ) below.
I've tested it with a RTX 4070 desktop version. Please let me know if this has any issues.
