fix: align linker output with Angular TypeScript compiler

[Brooooooklyn]

• fix deps: null to use ɵɵgetInheritedFactory instead of no-args constructor
• fix deps: 'invalid' to emit ɵɵinvalidFactory()
• add ForPipe flag (16) for Pipe dependency inject calls
• fix attribute: true to use token as arg to ɵɵinjectAttribute
• handle token: null deps with ɵɵinvalidFactoryDep(index)
• fix useClass != type without deps to delegate to useClass.ɵfac
• omit providedIn when null (matching TS behavior)
• refactor extract_deps_source to take target param, generate correct
  inject function directly instead of fragile string replacement
• only emit standalone: false (omit when true, matching TS default)
• remove extra type property from defineInjector output
• omit declarations/imports/exports from defineNgModule in AOT mode
• add id support and registerNgModuleType IIFE side-effect for NgModules
• fix link_injectable to use conditional factory pattern for useValue,
  useExisting, useFactory (with deps), and useClass (with deps)
• fix useFactory without deps to wrap as () => factory()
• fix useClass === type without deps to include __ngFactoryType__ param
• fix link_class_metadata_async to extract callback params and read
  decorators/ctorParameters/propDecorators from resolveMetadata return value

Close #89

Note

Medium Risk
Touches core linking logic for DI factories/injectables and NgModule/injector emission, which can change runtime behavior if mismatched. Risk is mitigated by extensive new regression tests covering the new edge cases.

Overview
Updates ɵɵngDeclareFactory linking to match Angular semantics for deps: treats deps: null as inherited (uses ɵɵgetInheritedFactory), deps: 'invalid' as ɵɵinvalidFactory(), emits ɵɵinvalidFactoryDep(index) for token: null, fixes @Attribute() handling to pass the dep token, and generates the correct inject function/flags directly (including Pipe ForPipe flag 16 and ɵɵdirectiveInject vs ɵɵinject).

Reworks ɵɵngDeclareInjectable linking to omit providedIn when unset/null and to use Angular’s conditional-factory pattern for useValue, useExisting, and useFactory/useClass (including delegating useClass != type to useClass.ɵfac and wrapping useFactory without deps as () => factory()).

Adjusts emitted definitions to omit standalone when it would be true (only emit standalone: false), removes the extra type field from defineInjector, changes defineNgModule output to omit declarations/imports/exports in AOT mode while adding id support via registerNgModuleType IIFE, and fixes ɵɵngDeclareClassMetadataAsync linking to derive callback params and metadata from resolveMetadata’s returned object. Adds comprehensive tests for all of the above behaviors.
