fix(core): resolve barrier immediately when target count is zero

A Barrier created with targetCount 0 never settled its promise because
signal() was never called for classes with zero constructor or property
dependencies, leaving one forever-pending promise per zero-dependency
class and tripping async-leak detection (e.g. Vitest detectAsyncLeaks).
Resolve eagerly in the constructor and make signal() idempotent past
the threshold to tolerate over-signaling from error paths.

Closes #17392
