v3.0.0 — TFTP Network Bootstrap

Highlights

• Adds the tiny standalone uget TFTP GET helper for large payloads.
• Adds the uart-push tftp workflow for staging uget over UART and downloading payloads over UDP with size and CRC32 verification.
• Adds architecture-aware helper and payload argument handling, atomic installation, retries, and cleanup.
• Documents the companion utftp UDP server workflow.

Breaking change

The CLI now requires an explicit direct or tftp subcommand. The previous root-level invocation syntax and --exec-args flag are removed.

Assets

Go binaries are provided for Linux, macOS, and Windows. The included static uget binary is x86_64; build uget from bootstrap/ for the target router architecture.
