Rename all trailing-underscore private data members to the m_ prefix
required by AGENTS.md, across the auth, crypto, gip, mt76, and usb
transport classes plus the app session classes. Pure rename; no
behavior change. Full build and test suite pass.

Defer RSA, ECDH, and handshake completion until after each received packet
has been added to the authentication transcript, matching the upstream
workqueue ordering and preventing the controller from rejecting host secret.
Co-Authored-By: openai/gpt-5.6-luna: fixed GIP authentication ordering
Port the GIP protocol and authentication layers from medusalix/xone
into the C++ stack:
- crypto: SHA-256/HMAC (CommonCrypto), RSA PKCS#1 (Security.framework),
and a self-contained P-256 ECDH validated against OpenSSL vectors
- auth: v1 (RSA) and v2 (ECDH) handshake state machine
- gip: header/varint/chunk handling and packet dispatch, with the kernel
device model replaced by transport + client_listener interfaces
Adds test_crypto, test_auth, and test_gip suites.
