Quick info & find-all-refs tests for JSDoc namespaces

Pull request overview

This PR extends the TypeScript-go port’s JSDoc namespace support by parsing dotted @typedef/@callback names as namespace chains and ensuring those reparsed declarations participate correctly in symbol visibility, Quick Info, and Find-all-references. It also adds new compiler + fourslash baselines/tests to lock in the language-service behavior, and updates impacted submodule baselines.

Changes:

• Parse dotted JSDoc names (NS.T, A.B.C) into namespace-shaped AST and wrap reparsed typedef/callback aliases into corresponding namespace declarations.
• Adjust “implicitly exported JSDoc declaration” handling so reparsed namespace wrappers behave as module-visible where appropriate.
• Add/refresh compiler and fourslash baselines for Quick Info verbosity + FindAllRefs on namespaced JSDoc typedefs; update affected submodule baselines/acceptance lists.
