Pull Request Overview

This PR enhances the parser to handle index signatures with multiple parameters (emitting an error if more than one is provided), updates diagnostics and codegen formatting, and aligns example code with the new parser API.

• Allow parsing multiple parameters in ts/types.rs and validate that exactly one is present.
• Add a new index_signature_one_parameter diagnostic and remove outdated doc comments in diagnostics.rs.
• Change codegen to render index signature parameters separated by commas and update examples to match the new parser return type.

• The call to parse_delimited_list already consumes the closing ]. The extra expect(Kind::RBrack) will look for a second ] and fail. Please remove this redundant expect.
