Add error recovery to the parser so that when a syntax error is encountered at the item level (function, struct, enum, etc.), the parser can skip tokens until finding the start of the next item and continue parsing. Key changes: - Add Item::Error and Expr::Error variants to AST for recovered error nodes - Implement error_recovery() parser using Chumsky's via_parser() strategy - Update all Item and Expr match exhaustiveness throughout the codebase - Add ErrorContains type to test runner for checking multiple error substrings - Add UI tests for multi-error reporting scenarios Before this change, the compiler would stop at the first parse error. Now it can report multiple errors in a single compilation, helping users fix more issues per compile cycle. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
