## [v0.1.13] 2026-06-14 New syntax + optimized grammar models

### Added

- New `@name`, `@int`, `@uint`, `@float`, `@bool` meta-expressions for
typed token matching (names, signed/unsigned ints, floats, bools)
- `Cursor.MatchName`/`MatchInt`/`MatchUInt`/`MatchFloat`/`MatchBool`
methods on `RuneCursor` and `StrCursor`
- `Ctx` interface methods that delegate to cursor matching
- Five concrete model types (`NameMeta`, `IntMeta`, `UIntMeta`,
`FloatMeta`, `BoolMeta`) with `MetaExp` base
- Full compilation pipeline: EBNF tree compile, JSON import/export,
analysis passes, display (pretty-print & railroads)
- 40 cursor-level tests ported from TatSu
- Boot grammar usage of `@name` in rule definitions

### Changed

- Meta expression dispatch updated from single `*MetaExp` type case to five individual type cases across the compiler pipeline
- All TatSu `@` meta features brought to parity with TatSu v5.21.1

### Changed

- Refactored grammar semantics from function type (`SemanticsFunc`) to `GrammarSemantics` interface in `pkg/config`; replaced
`GrammarParserSemantics` with `EBNFGrammarSemantics` struct adding meta-expression node production (`NameMeta`, `IntMeta`, `UIntMeta`, `FloatMeta`, `BoolMeta`) during boot grammar compilation of `@` expressions
