### Breaking changes

CodeMirror now uses lezer 0.15, which means different package names (scoped with @lezer) and some breaking changes in the library.

`EditorParseContext` is now called `ParseContext`. It is no longer passed to parsers, but must be retrieved with `ParseContext.get`.

`IndentContext.lineIndent` now takes a position, not a `Line` object, as argument.

`LezerLanguage` was renamed to `LRLanguage` (because all languages must emit Lezer-style trees, the name was misleading).

### New features

New `IndentContext.lineAt` method to access lines in a way that is aware of simulated line breaks.

`IndentContext` now provides a `simulatedBreak` property through which client code can query whether the context has a simulated line break.
