Description
The docs show HardwareState::Available(pinned). The parser handles simple enum variants (Expr::EnumVariant("PadMode", "Trim")), but it does not support parsing or storing associated data in enum variants.
Tasks:
- Update
EnumVariantparsing to optionally accept a tuple or struct-like payload (e.g.,(pinned)). - Update AST to represent this payload.

Research direction
Start by locating the parser entry point for simple EnumVariant expressions and the AST definition for Expr::EnumVariant. Trace how tuple-like and struct-like payloads are represented, then update parsing and AST storage so examples such as HardwareState::Available(pinned) are accepted and represented consistently; add or update parser tests if the project has them.
