chore: bump chumsky from 0.11.2 to 0.12.0

[dependabot]

Bumps chumsky from 0.11.2 to 0.12.0.

Changelog

Sourced from chumsky's changelog.

[0.12.0] - 2025-12-15

Added

• MapExtra::emit, which allows emitting secondary errors during mapping operations
• InputRef::emit, which allows emitting secondary errors within custom parsers
• labelled_with, which avoids the need to implement Clone for labels
• Input::split_token_span, a convenience function for splitting (Token, Span) inputs so that chumsky can understand them
• Input::split_spanned, which does the same as above, but for implementors of WrappingSpan
• spanned, a combinator which automatically annotates a parser output with a span
• Experimental:
  • IterParser::parse_iter, a way to turn an IterParser (like x.repeated()) into an iterator
  • Parser::debug, which provides access to various parser debugging utilities.

Changed

• Made nested_in more flexible by allowing it to map between different input types instead of requiring the same input as the outer parser

Fixed

• A prioritisation bug with nested_in

Fixing chumsky 0.12.0 upgrade ✅

• Check CI status to understand failures
• Regenerate Cargo.lock to include all transitive dependencies
• Run tests locally (636 tests passed ✅)
• Push changes
• CI passed ✅

Issue found & fixed: The Dependabot PR incorrectly removed chumsky 0.11.2 from the lockfile. This project requires both versions:

• chumsky 0.12.0 for non-wasm targets
• chumsky 0.11.2 for wasm targets

Regenerated the Cargo.lock to include both versions. All tests passed locally and CI is now green.
