v1.3.0: Add 14 keyfob protocols (8 ProtoPirate + 6 Flipper-ARF), fix KeeLoq overflow

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.
