feat: improve error messages with tsc-style diagnostics (#30)

* feat: add Diagnostic class for unified error structure

- Add Diagnostic class with code, message, file, line, column attributes
- Add factory methods: from_type_check_error, from_parse_error, from_scan_error
- Add comprehensive tests for all functionality
- TR1xxx codes for parser errors, TR2xxx for type errors

* feat: add DiagnosticFormatter with tsc-style output

- Format errors as file:line:col - severity CODE: message
- Display source code snippets with line numbers
- Show error markers (~~~) under problem location
- Include Expected/Actual/Suggestion context
- Support ANSI colors with TTY auto-detection
- Format summary line: Found X errors and Y warnings

* feat: add ErrorReporter for collecting and reporting errors

- Collect multiple diagnostics during compilation
- Convert TypeCheckError, ParseError, ScanError to Diagnostic
- Auto-load source from file when not provided
- Report formatted output using DiagnosticFormatter
- Track error vs warning counts

* feat: integrate ErrorReporter into CLI

- Use ErrorReporter for TypeCheckError, ParseError, ScanError
- Display tsc-style formatted error output
- Include source code snippets and error markers
- Show Expected/Actual/Suggestion context
- Display summary line with error count

* refactor: use DiagnosticFormatter in Watcher

- Replace hash-based error format with Diagnostic objects
- Use DiagnosticFormatter for consistent tsc-style output
- Include source code snippets in watch mode errors
- Update tests to expect Diagnostic objects

* feat: add location info to MethodDef for better error messages

- TokenDeclarationParser: capture def token's line/column
- Parser.parse_function_with_body: add line/column to func_info
- Parser.parse_method_in_class: add line/column to method_info
- IR CodeGenerator.build_method: pass location to MethodDef

Error messages now show exact line:column position:
