Pull request overview

This PR improves error reporting for missing initializers in variable declarations by narrowing the span to highlight only the identifier name instead of the entire declaration including type annotations. This makes error messages more precise and focused.

Key Changes:

• Simplified span calculation for missing initializer errors in const declarations
• Simplified span calculation for missing initializer errors in using declarations
• Updated test snapshots to reflect the shorter, more focused error spans

File	Description
crates/oxc_parser/src/js/declaration.rs	Modified error span for missing initializers in both check_missing_initializer() and parse_using_declaration() to use only the identifier span instead of merging identifier and type annotation spans
tasks/coverage/snapshots/parser_typescript.snap	Updated 26 test case snapshots showing the new shorter error spans that highlight only the identifier in missing initializer errors
tasks/coverage/snapshots/parser_babel.snap	Updated 2 test case snapshots showing the new shorter error spans for const declarations without initializers
