v2.0.0

MAJOR: the base preset refuses the TypeScript syntax that Node cannot strip.

Breaking changes

• base.json sets erasableSyntaxOnly. Each preset extends it. Thus tsc gives the error TS1294 for an enum, a namespace with code, and a parameter property, for example constructor(private x: number).
• The reason: Node runs a .ts file only when it can strip the types. With such syntax, node stops at the start with ERR_UNSUPPORTED_TYPESCRIPT_SYNTAX, but tsc and vitest accept the file. On 2026-11-03 a parameter property stopped a scheduled run of a tool at the start, and its tests passed.
• To update: change an enum to an object as const and a union type of its values. Change a parameter property to a field and an assignment in the constructor.
• A package that cannot change sets "erasableSyntaxOnly": false in its own tsconfig.json. The rule cue-preset of @mark1russell7/conventions reports it, so the package also keeps an exception with its reason.
• The schema of a tsconfig.json has the option erasableSyntaxOnly.
