zarzet 088bd875dd refactor(core): move the lenient Go-style JSON decoder to core::json
The case-folding, null-tolerant struct decoder (`go_deserialize!` with
`field_name`, `KeySeed`, `Update` and `Field`) lived in `core::lyrics::json`
although downloads, metadata and resolver payloads depend on it. Move it
unchanged to a neutral `core::json` module and name the macro after its
behavior, `lenient_deserialize!`. All users are inside spotiflac-core, so no
compatibility re-export is kept. The lyrics module keeps only its
surrogate-normalizing `decode` helper.

`field_name` is now public so the extension registry decoder reuses it
instead of its own copy of the same folding. Its matcher folds the key once
and compares ASCII case-insensitively against the wire name, which a new
test checks against the previous matcher on edge inputs (empty, long s,
Kelvin sign, combining marks, non-ASCII letters, BOM, NUL).

The visitor's `expecting` text is unchanged so decode errors stay
byte-identical.
