Brings KAT to 32 protocol decoders. Ported from the ProtoPirate reference and the D4C1-Labs/Flipper-ARF firmware: ProtoPirate (8): Kia V7, Ford V1, Ford V2, Ford V3, Chrysler V0, Honda Static, Honda V1, Land Rover V0. Flipper-ARF (6): Toyota, Land Rover RKE, Mazda Siemens, BMW CAS4, Porsche Cayenne, PSA2. Each decoder is gated (CRC / checksum / fixed markers / frame structure) so it cannot false-match existing protocols; every previously-decoding IMPORTS capture decodes unchanged. Real-capture decodes added for Ford V3 (LDV T80), Honda Static (Honda), Toyota (Camry NRZ variant), and PSA2 (Groupe PSA, serial 0x99EB25); the rest are validated by encode/decode round-trip and synthetic-frame tests. Also fixes a debug-only underflow panic in keeloq_common::keeloq_decrypt (15 - r underflowed; now wrapping_sub to match the reference's unsigned wrap; release behavior unchanged). Adds per-protocol docs, updates the README protocol table, capture metadata (encoding / RF / encryption), make-suggestion mapping, and CHANGELOG.

KAT Protocol Documentation
This folder describes how each keyfob protocol supported by KAT works. Each document corresponds to a decoder/encoder in src/protocols/.
Capture/encode model: Decoded signals expose optional extra (e.g. VAG: vag_type + key_idx). When present, the app stores it in Capture.data_extra so retransmit can encode from the capture without decoder instance state. See vag.md for the VAG encode-from-capture flow.

KeeLoq generic is not a registered decoder; it runs when no protocol matches and tries KeeLoq with every keystore manufacturer key (using keeloq_common). Successful decodes appear as Keeloq (keystore name).
Implementations are aligned with the ProtoPirate reference in REFERENCES/ProtoPirate/protocols/.
