Correctness & safety

• RFC 868 client sends UDP request first; TCP fallback added
• Network timeouts on HTTP, daytime, and time protocol
• HTTP dates parsed with multiple formats; non-2xx responses rejected
• Daytime parsing supports multiple layouts; --time-is-utc for zoneless banners
• NTP responses validated; kiss-of-death rejected
• Clock offset applied at set time, not at fetch time
• Non-NTP sources corrected for one-way delay (RTT/2)
• --dry-run, --max-delta, and --force safety guards added
• --system-tools fixed for Linux, macOS, and Windows
• Syscalls moved to golang.org/x/sys (32-bit safe)
• NTP queries use hostname directly (IPv6, ports, pool DNS preserved)
• High-accuracy mode uses sequential spaced samples with median RTT
• Persistent flags fix ntpcl --set ntp HOST
• windows-time help clarifies unsigned NTP

CLI & output

• JSON, unix, rfc3339, quiet, and --no-color output formats
• Richer NTP table (version, reference ID, leap indicator, etc.)
• Typed errors with distinct exit codes (2–5)
• Module path changed to github.com/earentir/ntpcl
• README updated for subcommand-based CLI

Build & release

• Makefile added: make → native ./ntpcl, make all → static builds/ binaries
• Release targets: builds/ntpcl (linux/amd64), builds/ntpcl.exe (windows/amd64), builds/ntpcl_darwin (darwin/arm64)
• builds/ gitignored; static builds only (CGO_ENABLED=0)
• Darwin and Windows cross-compile fixes for release builds
