restore: expanded C headers + C MLD helpers + Rust MLD driver logic (Phase 6.2 full)

Restored the comprehensive Mini-MLD layer with the correct architecture: C headers = ABI contract, C transport = inherited legacy, Rust = driver logic, C MLD helpers = thin transport bridge. Files restored from git history (commit eeddbc72fe + b22fa7e24c): C headers (linux-kpi, ABI contract matching Linux fw/api/*.h): mac80211.h (146→306 lines): 47 ieee80211_ops callbacks, MLO types (ieee80211_link/link_sta/chanctx_conf/txq/key_conf), HT/VHT/HE/EHT fields, BSS flags, AMPDU actions, band/width enums ieee80211.h (27→183 lines): frame types, capabilities, cipher suites, IE IDs (40+), HT/VHT/HE/EHT capability structs Rust driver logic (redbear-iwlwifi/src/): mld.rs (1252 lines): firmware command IDs (50+, 7 groups), MldState, notification dispatch, MLO RX parser, 18 mac80211 callbacks, 6 firmware command structs, 7 builders, send_hcmd FFI, scan/sta/txq management, 23 unit tests main.rs: mod mld; integration C transport bridge (redbear-iwlwifi/src/): linux_mld.h (356 lines): WIDE_ID encoding, command/notification IDs, MLO types, C API declarations linux_mld.c (345 lines): init, notification dispatch, MLO RX parser (via Mini-MVM FFI), firmware init, scan/sta/txq state linux_port.c: function signatures updated to match expanded mac80211.h ops (tx: sk_buff→txq, bss_info_changed: u32→u64, set_key: key_params→ieee80211_key_conf), opmode gate, mld_state, status line Rust mac80211.rs: Ieee80211Ops with 47 callback fields, MLO Vif/Sta build.rs: compiles linux_mld.c alongside linux_port.c + linux_mvm.c Architecture: C headers = firmware ABI (match Linux 1:1), C transport = inherited legacy (proven working), Rust mld.rs = driver logic, C MLD helpers = transport bridge. 23 tests pass.
