Fixes #632.

Problem

A standalone component listed as imports: [forwardRef(() => CmpA)] and used only inside @defer stayed eager: the implicit-deferral gate from #313 required every imports entry to be a bare identifier, and the identifier list it matched against skipped forwardRef(...) entries. The static import { CmpA } stayed and ɵɵdefer(1, 0) got no dependency function. ngtsc resolves the entry through forwardRefResolver (tryUnwrapForwardRef in packages/compiler-cli/src/ngtsc/annotations/common/src/util.ts) before resolveAllDeferredDependencies matches selectors.

Fix

• decorator.rs: record the classes written as forwardRef(() => X) in the imports array (ComponentMetadata::forward_ref_imports), using the existing try_unwrap_forward_ref, so only @angular/core's forwardRef counts. imports itself is unchanged (partial/Direct emit still reads it).
• transform.rs: import_entry_class maps each raw imports entry to its class (X or a resolved forwardRef(() => X), arrow or return body). The gate, the candidate list and the removal from the eager ɵɵgetComponentDepsFactory array all use it.

Output now matches ngc: ɵɵdefer(1, 0, () => [import("./lazy").then(m => m.LazyCmp)]), ɵɵgetComponentDepsFactory(Parent, []), and no static import.

Selectorless deps (selectorless_spec.ts: "should defer selectorless symbols") are out of scope: OXC rejects selectorless components outright (pipeline/ingest.rs), so there is nothing to defer yet.

Checks

• New in tests/defer_implicit_imports_test.rs: forward_ref_import_used_only_inside_defer_is_lazy_loaded (port of defer_spec.ts "should lazy-load dependency referenced with a fowrardRef", arrow and block-body forms) and forward_ref_not_from_angular_core_stays_eager.
• cargo test -p oxc_angular_compiler --all-features: 3518 passed, 0 failed.
• cargo fmt; cargo clippy -p oxc_angular_compiler --all-features adds no warnings on the changed lines.
