Address Copilot review round 2: - Remove PROFILE variable and hardcode --release / target/release/. Cargo maps "dev" profile to target/debug/ (not target/dev/), so PROFILE=dev would silently break install. Nobody installs debug builds of setuid-root tools. - Fix stale comments in Makefile and README that referenced the old "chmod on symlink follows through" approach. The current code uses install -Dm4755 directly.
