feat: scaffold fifa-blaze Blaze protocol emulator (Milestone 1)

Two-crate workspace: blaze-proto (Fire2 framing via tokio_util codec,
tdf=0.1 for TDF decode/stringify) and server (TLS listeners for
redirector + Blaze, JSONL capture with TdfStringifier, pluggable
FramingVariant enum).

Both listeners bind on startup and write a capture JSONL for every
packet. Component/command IDs are unknown — captures reveal them.
