Split out of #26862, as discussed there. - `LSPFileSystem` stores the version reported by `textDocument/didOpen` and `textDocument/didChange` next to the content (`set_with_version`, `get_version`); `set`, used for `didSave`, keeps the stored version since that notification carries none. The API follows #23796, on `main`. - `TextDocument` carries the version (`None` for content read from disk) and `CodeActionParams` carries `document_version: Option<i32>` instead of `is_open_document`, which is `Some` exactly when the document is open. A `didSave` carrying text for a document which is not stored (a conforming client never sends one, since `didSave` only follows `didOpen`) still creates the entry as before, now with version 0. No behaviour change: nothing reads the version yet. The code-action cache keyed by it, and the `source.fixAll` fix of #26862, come separately on top of this. Tests: `LSPFileSystem` versions, and the backend wiring (`didOpen` 1 → `didChange` 2 → `didSave` keeps 2 → `didClose` none). Worth knowing: `CodeActionParams.is_open_document` becomes `document_version` and `TextDocument` gains a `version` field, which touches any external `Tool` implementor.

/oʊ ɛks siː/
The Oxidation Compiler is a collection of high-performance tools for JavaScript and TypeScript written in Rust.
Oxc is part of VoidZero's vision for a unified, high-performance toolchain for JavaScript. It powers Rolldown (Vite's bundler) and enables the next generation of ultra-fast development tools that work seamlessly together.

🙋 Who's using Oxc?
Rolldown and Nuxt use Oxc for parsing. Rolldown also uses Oxc for transformation and minification. Nova, swc-node, and knip use oxc_resolver for module resolution. Preact, Shopify, ByteDance, and Shopee use oxlint for linting.
