feat: bundle tkinter into Windows portable build 
Download _tkinter.pyd, tkinter package, and Tcl/Tk DLLs from the
official Python nuget package and copy them into the embedded Python
directory. This enables the screen overlay visualization during
calibration in the portable build.

# Cross-build a portable Windows distribution of LedGrab from Linux.
#
# Downloads Windows embedded Python and win_amd64 wheels — no Wine or
# Windows runner needed. Produces the same ZIP as build-dist.ps1.
#
# Usage:
# ./build-dist-windows.sh [VERSION]
# ./build-dist-windows.sh v0.1.0-alpha.1
#
# Requirements: python3, pip, curl, unzip, zip, node/npm
