fix(compiler): handle @Inject(TOKEN) on pipe constructor params (#231)

The extract_param_dependency function in pipe/decorator.rs was missing
the "Inject" arm in its decorator match, causing @Inject(TOKEN) to be
silently ignored. The injection token was then extracted from the TypeScript
type annotation instead — which is undefined at runtime when the type is
an interface.

The same fix already exists in directive/decorator.rs and
injectable/decorator.rs. This brings pipe/decorator.rs in line.

Surfaced by Angular 20 which added an assertDefined(token) guard in the
DI runtime that throws immediately on an undefined token, whereas Angular
19 would silently pass through.
