The only existing installer (install.sh) is bash-only and fails silently
on Windows PowerShell — 'curl ... | bash' errors because bash.exe is not
available outside WSL.
install.ps1 implements the same logic as install.sh for PowerShell:
- Checks bun >= 1.2.0; installs via bun.sh/install.ps1 if missing
- Downloads CLI source via git sparse-checkout or GitHub API fallback
- Builds with 'bun install && bun run build'; falls back to pre-built binary
- Installs to %USERPROFILE%\.local\bin (or SPAWN_INSTALL_DIR override)
- Creates spawn.cmd wrapper for cmd.exe compatibility
- Adds install dir to the user's persistent PATH if not already present

the existing macOS/Linux/WSL command.
