Tape Decode v3.0.0

Decode Launcher (decode-rust-gui)

This release ships the Decode Launcher ("decode-rust-gui") with built-in support for x86-64 microarchitecture level selection (Auto / v1 / v2 / v3 / v4).

The decode-rust-gui binary is the primary artifact. It provides the GUI when launched normally, and full CLI functionality when invoked from a terminal (e.g. decode-rust-gui list-profiles, decode-rust-gui decode ...). No separate raw tape-decode binary is released.
