docs: evaluate tsdeclarations codegen, map permissions, verify encoding (TODO-063,068,069)

tsdeclarations eval: direct codegen redundant (already via tsproto),
but permission ID generation and error code enum have high value.
Permission mapping: 253 TS3 permissions identified, 7 P1 for chat/moderation.
Encoding verification: tsclientlib uses strict UTF-8, UCS-2 is edge case.

 - **Description:** TS claims UTF-8 but uses UCS-2 (BMP only). Mobile apps use CESU-8. Server 3.2.0+ adds partial emoji support. tsclientlib/tsproto delivers Rust `String` (UTF-8) via `str::from_utf8()` at the protocol layer (ReSpeak §1.8.3 confirms: "Command string encoded in UTF-8"). If encoding bugs exist, the fix belongs in the EdisonJwa/tsclientlib fork, not in chanora_protocol.
