install.sh

#!/usr/bin/env bash
# SIN-Code one-line installer (issue #170): downloads the single static
# sin-code binary from the latest GitHub release. Settle into a writable
# bin dir ($SIN_CODE_BIN_DIR or $HOME/.local/bin) and delegate to
# `sin-code install --auto` so the Go entrypoint handles SHA256 verify
# and atomic placement. Mirrors install.ps1 for Windows.
#
# Usage:
#   curl -fsSL https://raw.githubusercontent.com/OpenSIN-Code/SIN-Code/main/install.sh | bash
#   SIN_CODE_BIN_DIR=~/my-tools bash install.sh --release=v3.17.0
