- Add Windows 4.1.x Config.Cipher pointer-chain key extraction with cross-chunk
MemoryPatternScanner and bounded blob XOR decoding; keys still require per-DB
page-1 HMAC verification before caching.
- Cache keys by account fingerprint + database relative path; db scan --save
skips memory scanning entirely once all discovered databases are cached.
- Add DbMessage model (localId, serverId, type, timestamp, sender, display name,
avatar, isSelf) read read-only from Msg_{md5(chat)} via SQLCipher with hex/zstd
content decoding and contact.db name resolution.
- CLI: db messages / db contacts / db schema with masked defaults; include the
earlier chat send --session wiring. 97 Core tests pass; real-machine validated.
