# This is a **reuseable** workflow that builds the CLI for multiple platforms.
# It doesn't get triggered on its own. It gets used in multiple workflows:
#  - release.yml
#  - canary.yml
#
# Platform Build Strategy:
#  - Linux: Uses Ubuntu runner with cross-compilation
#  - macOS: Uses macOS runner with cross-compilation  
#  - Windows: Uses Ubuntu runner with Docker cross-compilation (same as desktop build)
