9327d5d3 - [ty] Fulfill language-server requests against closed documents (#28595)

[ty] Fulfill language-server requests against closed documents (#28595) ## Summary This allows language-server clients to request document symbols, hover information, and other document features without first sending `textDocument/didOpen`. Requests can target local files within workspace folders or configured import search paths, as well as cached copies of ty's bundled typeshed stubs. This includes files excluded from type checking (e.g., through [`src.exclude`](https://docs.astral.sh/ty/exclusions/)). Fixes https://github.com/astral-sh/ty/issues/3624. ## Approach Existing request handlers can now read closed documents through the selected project's database without registering those documents as open. Additionally: - Open documents continue to use the client's text, including unsaved edits. - Requests against closed documents preserve the existing diagnostic policies and do not add files to the set selected for type checking. For example, `openFilesOnly` mode returns no diagnostics for closed documents. - Unopened notebooks remain unsupported because the client supplies their cell URIs and position mappings. ## Test Plan See included tests.
