Summary

This fixes five small places where our output differs from ngtsc (@angular/compiler-cli 22.2.3). Part of #623.

#	Shape	Before	After (same as ngtsc)
1	A ctor param with no usable token	ɵɵinvalidFactoryDep(n)	the whole factory becomes ɵɵinvalidFactory() (full) / deps: "invalid" (partial). Port of unwrapConstructorDependencies (annotations/common/src/di.ts)
2	NgModule schemas	listed in ɵmod	left out of ɵmod, because the handler passes schemas: [] (ng_module/src/handler.ts, FW-1004). setClassMetadata still lists them
3	Directive query predicates	inline arrays	pooled as const _c0 = [...], content queries first (baseDirectiveFields, render3/view/compiler.ts). Host binding constants keep counting from there
4	Default-imported token	i1.default	Foo (typeToValue's LOCAL ref plus defaultImportStatement)
5	@Inject(TOKEN) token	i1.TOKEN / i0.DOCUMENT	TOKEN / DOCUMENT, as written (getConstructorDependencies)

Import elision follows these changes:

• The import of an @Inject token is kept, with or without class metadata.
• A default import used only as a ctor param type is kept when the factory or the metadata uses it.
• With no metadata, @Inject / @Attribute replace the type as the token. Nothing uses Foo then, so its import is dropped, as in ngtsc.

Example: default import replaced by @Inject (no class metadata)

import Foo from './foo';            // export default interface Foo {}
import { TOKEN } from './tok';
@Injectable() export class S { constructor(@Inject(TOKEN) f: Foo) {} }

Before:

import Foo from './foo';   // kept, but nothing uses it
import { TOKEN } from './tok';
... new (t || S)(i0.ɵɵinject(TOKEN))

After / ngtsc:

import { TOKEN } from './tok';
... new (t || S)(i0.ɵɵinject(TOKEN))

ngtsc parity cases checked

All were run through performCompilation. ngtsc's "no metadata" mode is supportTestBed: false (full mode only):

• @Inject(TOKEN) f: Foo on an @Injectable and on a @Component, no metadata: Foo import dropped
• @Attribute('x') f: Foo on a @Directive, no metadata: dropped
• @Optional() f: Foo and plain f: Foo, no metadata: kept (ɵɵinject(Foo, 8) / ɵɵinject(Foo))
• @Inject(TOKEN) f: Foo with metadata: kept (type: Foo in ctorParameters)
• Earlier rounds: invalid deps, schemas, query pooling, default-import tokens and @Inject tokens, in full and partial mode

Checks

• cargo test --all-features: 3608 passed, 0 failed
• conformance: 1264/1264, snapshot unchanged
• clippy: no new warnings on changed lines
• napi build-test, then vitest: 21 files, 397 tests passed. tsc --noEmit is clean. No TS files changed in this round.
• The new test default_import_overridden_by_inject_or_attribute_is_elided_without_metadata fails when src/ is stashed and passes with the change.
