fix: use GitHub 'latest' release URL in install_hero.sh

- Remove hardcoded version, use releases/latest/download instead
- Always use musl builds for Linux (static binary works everywhere)
- Fix variable name bugs (OSNAME -> os_name, OSTYPE -> os_name)
- Only modify .zprofile on macOS (not Linux)
- Remove dead code
