- Vanilla M2 bone struct (108 bytes) with 28-byte animation tracks - Version-aware bone parsing (vanilla vs WotLK format detection) - Fix CharSections.dbc field layout for vanilla (variation/color at 4-5) - Remove broken CharSections.csv files (all fields marked as strings) - Expansion data reload on profile switch (DBC cache clear, layout reload) - Vanilla packet encryption (VanillaCrypt XOR-based header crypt) - Extended character preview geoset range (0-99) for vanilla models - DBC cache clear support in AssetManager

* Key Differences from Auth Server:
|
|
* - Outgoing: 6-byte header (2 bytes size + 4 bytes opcode, big-endian)
|
|
* - Incoming: 4-byte header (2 bytes size + 2 bytes opcode)
|
|
* - Headers are encrypted after CMSG_AUTH_SESSION
|
|
* - Packet bodies remain unencrypted
|
|
* - Size field includes opcode bytes (payloadLen = size - 2)
