authdog-cli install worker

Linux / macOS:
  curl -fsSL https://cli.auth.dog/install | bash

Windows (PowerShell):
  iwr -useb https://cli.auth.dog/install.ps1 | iex

Resolve download URL for a Rust triple (see GitHub Release workflow matrix):
  curl -fsSL 'https://cli.auth.dog/v1/binary-url?target=x86_64-unknown-linux-gnu'

Pin a version (bare semver tag, same as GitHub release tag — no leading v):
  curl -fsSL 'https://cli.auth.dog/v1/binary-url?target=aarch64-apple-darwin&version=0.1.0'

Notes:
- Omitting version prefers the latest stable release; prereleases are used only when no stable exists yet.
- Linux: set AUTHDOG_CLI_USE_MUSL=1 before piping install for static musl builds (x86_64 / aarch64 only).
- Override install dir: INSTALL_DIR=/usr/local/bin (POSIX) or $env:INSTALL_DIR (PowerShell).
