# =============================================================================
# Downloads the latest Owl Sidecar release for your platform from GitHub
# Releases, installs the binary to ~/.owl-sidecar/bin, and adds a shim to
# ~/.local/bin/owl-sidecar. Works on macOS (Apple Silicon) and Linux (x64,
# arm64). On macOS it also clears the quarantine flag.
#
# To install the macOS app instead, download owl-sidecar-<version>-macos-arm64.tar.gz
# from the releases page and move OwlSidecar.app to /Applications. The app is
# notarized and needs no extra steps. On Windows, download the zip and run
# owl-sidecar.exe.
