subotac opened PR #14068 from subotac:fix/fixed-length-list-wave-printing to bytecodealliance:main:

Fixes #13984.

wasm-wave treats fixed-length lists as list-like values when formatting, but Wasmtime's WasmValue::unwrap_list only accepted Val::List. This caused the CLI to panic while printing a fixed-length-list result.

Allow the list unwrapper to iterate over Val::FixedLengthList and add a regression using the reported component that verifies the [7] output.

Tests:

- cargo test --test all component_model::fixed_length_list::
- cargo test --test all
