Opening a `.rs` file in the code panel silently spawned rust-analyzer, which then indexed the whole workspace — hundreds of megabytes of RAM and a busy core — with no setting to turn it off. A terminal emulator should not do that to its user on a click, and rather than add a flag to disable something nobody asked for, the integration goes. Removed: the JSON-RPC client and reader thread (`ui::lsp`), the per-server registry, the completion / hover / definition providers installed on the buffer, document sync (didOpen/didChange/didSave/didClose), diagnostics, Go to Definition (F12), Find References (⇧F12) and its drawer, and the status bar's server indicator. With them go the `lsp-types`, `ropey` and `url` dependencies — all three were used only by this code (they remain in the lock file as transitive deps of gpui-component and gpui, which is expected). Kept, and deliberately so: - **Syntax highlighting**, which is tree-sitter, not LSP: gpui-component's `tree-sitter-languages` feature, `InputState::code_editor(language)` and `language_for_path` are all untouched. It is static, in-process, and costs nothing beyond parsing the open buffer. - ⌘S save, dirty tracking, the external-change watcher and its conflict banner, markdown preview, soft wrap, and open-from-the-file-tree. The module header now records *why* there is no language server, so the next person to reach for one finds the reasoning instead of a gap. Net −975 lines.
