AI Summary: The `source.organizeImports` code action in TypeScript is reported to incorrectly remove re-exports. This bug specifically occurs when a module mixes both wildcard and non-wildcard re-exports, leading to necessary exports being deleted. The issue is observed with TypeScript 5.9.3 and `typescript-language-server` 5.0.1, triggered via Neovim's LSP.

AI Summary: The 'Move to file' refactoring feature fails when attempting to move a variable that utilizes an imported dependency as a template string tag function. The issue is reproducible with examples demonstrating failure for imported tags (e.g., `dedent`) while working correctly for local, undeclared, or non-existent imported tags. This indicates a bug in how the refactoring tool identifies and handles import statements for such dependencies during a move operation.
