${...} template-literal interpolation in decorator metadata not statically evaluated

[brandonroberts]

When a decorator's template: or selector: is a JS template literal interpolating a module-level const, OXC fails to evaluate it — either bailing entirely (no ɵcmp) or compiling with an unresolved selector.

Repro

import { Component } from '@angular/core';
const twBtn = `px-4 py-2 rounded`;
@Component({ selector: 'app-btn', template: `<button class="${twBtn}">x</button>` })
export class BtnComponent {}

Actual

Emits the verbatim @Component source — no ɵcmp. With ${...} in selector:, compiles but emits selectors: [["ng-component"]].

Expected

Angular's partial evaluator resolves const-bound (incl. nested/chained) template literals in static metadata fields. OXC already handles styles: correctly — only template:/selector: regress. Commit a2e5d4d (#271) covered plain string consts but not template-literal consts.

Impact

AOT — an uncompiled component is dead at runtime; an unresolved selector silently never matches its tag.
