Two changes that make AACS 1.0 / DVD self-sufficient: 1. MKB record-type identification bug fix. `mkb_find_mk_dv` was searching for type 0x10 (which is Type-and-Version, 12 bytes) when the Verify Media Key Record is actually type 0x81 for AACS 1.0 or type 0x86 for AACS 2.0/2.1. `mkb_version` had the inverse bug. PK and DK derivation paths therefore silently failed on every disc, masking how often the fallback paths could have worked. Fix searches the correct types; tests added covering both the 0x81 and 0x86 verify-record forms and the 0x10 version record at offset 8 of the body. 2. Built-in AACS keys + operator plugin slot. Four device keys (covering MKB v01-v82+) and three processing keys (covering v63-v68) compiled directly into the library. Combined with the 31 CSS player keys already in css/auth.rs, DVDs and Blu-rays (AACS 1.0) now decrypt with zero external files. New plugin path at ~/.config/freemkv/local_keys.cfg (same syntax as keydb.cfg) layered additively on top of built-ins and main keydb. `Disc::scan` no longer errors when keydb.cfg is absent; AACS 2.0 / UHD still surfaces a specific error when the disc needs keys none of the layers provide. Public docstrings in project docs + README updated to describe the three additive layers (built-ins → keydb.cfg → local_keys.cfg).
