🔖 chore: number the legacy-decorator line 0.1.x, not 1.x

Nothing has been published, so a 1.0.0/2.0.0 split claimed a stability and a
history that do not exist. Staying on 0.x says what is true: the API may still
move. Under semver a breaking change is then a minor bump, which is exactly the
relationship between the two lines — 0.1.x keeps legacy experimentalDecorators,
0.2.x moves to TC39 standard decorators.

Branch renamed 1.x -> 0.1.x to match, along with its CI trigger and the
maintenance-line notice in the README.

+The legacy-decorator line, now maintained in parallel with 0.2.x. Functionally identical

 # Cereale
 
+> **This is the 0.1.x maintenance line**, which uses TypeScript's legacy
+> `experimentalDecorators`. It is feature-complete and supported for bug fixes.
+>
+> **New projects should use 0.2.x**, which moves to TC39 standard decorators and gains
+> compile-time checking of validation rules against field types — `@IsString() age: number`
+> becomes a compile error rather than a runtime surprise.

+> Stay on 0.1.x if your toolchain transpiles with **oxc**, which does not yet implement the

 Cereale is a lightweight TypeScript library that provides Spring-like decorators for JSON mapping and validation. Built with ZERO external dependencies, it simplifies the process of converting between plain JSON and class instances with full validation support.
