fix: resolve Windows build issues

[embogomolov]

• Replace Unix-specific cp -r command with cross-platform Node.js cp() function
• Add icon.ico to Tauri bundle configuration to fix Windows bundling

These changes enable successful builds on Windows systems

there is a format issue about icon.ico.

i personally had to copy and replace the runCommand function from fetch-and-build.js into build-executables.js and replace the icon.ico (i converted icon.png into an icon.ico 256x256 32bit)

[rikodot]

also had to update bundled claude code version as i cant use any other than the bundled version for some reason:

1. i install latest version via npm (npm install -g @anthropic-ai/claude-code)
2. find install path (where claude), in my case it was C:\Program Files\nodejs and from there i go to C:\Program Files\nodejs\node_modules\@anthropic-ai\claude-code
3. open cli.js and search for import.meta.url).resolve("./yoga.wasm"
4. in scripts/prepare-bundle-native.js i change yogaLoadPattern and yogaLoadReplacement accordingly (this changes with each claude code version)
5. just to be sure i replaced all references to old version of claude code in scripts/fetch-and-build.js (from 1.0.41 and 1.0.42 to 1.0.51 you find this out via claude --version)
6. in package.json change all references to old version as well so from --version=1.0.41 or --version=1.0.42 to --version=1.0.51
