Pull request overview
This PR fixes TypeScript enum member symbol span tracking in the semantic binder so that enum member symbols are associated with the span of the member name (not the entire enum member including its initializer), and adds an integration test to prevent regressions.
Changes:
- Bind
TSEnumMembersymbols usingself.id.span()instead of the full memberspan. - Add an integration test asserting
symbol_spanfor an enum member resolves to just the identifier text.

Fixes TS enum member symbols so their stored span points at the member name instead of the entire enum member declaration. The previous span used `TSEnumMember::span`, which includes initializer text like `A = 1`.

The previous span used
TSEnumMember::span, which includes initializer text likeA = 1.
