CodeMirror Rome Formatter IR Mode

A CodeMirror 6 language mode that provides syntax highlighting and code editing support for the Rome formatter intermediate representation (IR). This package is at an early, unstable version (0.0.2) with slow or inactive release cadence. Unlike general-purpose CodeMirror modes, this one is purpose-built for the Rome IR format used in the Rome formatter's internal representation. It ships TypeScript definitions and is intended for integration with CodeMirror 6 projects that need to inspect or debug Rome's formatter IR.
