[dependabot]

Bumps langium from 4.3.1 to 4.4.0.

Changelog

Sourced from langium's changelog.

v4.4.0 (Sep. 2026)

• Significantly reduce the memory usage of the CST and improve parsing performance (#2191).
• Support priority read requests to prevent LSP requests from operating on outdated data (#2214).
• Implement the LSP 3.18 workspace/textDocumentContent request via the new TextDocumentContentProvider service (#2190).
• The default completion provider now supports both the insert and replace suggestion modes (#2211).
• Test assertions now accept lazily computed error messages (#2208).
• Update Chevrotain to v13 (#2196).
• Update vscode-languageserver to 10.1 and vscode-languageserver-protocol to 3.18.2 (#2184).
• Fix streaming of array-valued multi-references (#2220).
• Fix JSON deserialization of multi-references (#2181).
• Fix MapScope using its outer scope even when it is disabled (#2210).
• Improve customizability of URI normalization in the UriTrie (#2209).

Breaking Changes

• As part of the CST memory optimization (#2191), CstNode#root is no longer stored but derived from the container hierarchy, and CompositeCstNode#content is now a readonly array that must be manipulated via the CstNodeBuilder.

v4.3.0 (Jun. 2026)

• Update LSP support to version 3.18 of the protocol (#2165).
• Improve memory usage of references (#2161).
• Add a isComplete check to the AST reflection service (#2155).

Breaking Changes

• As a consequence of the LSP version upgrade, Langium now requires updated versions of the language-server packages:
  • "vscode-languageserver": "~10.0.0"
  • "vscode-languageserver-protocol": "~3.18.0"
  • "vscode-languageserver-types": "~3.18.0"
