feat(Factory): prevent service modifications after provider is built

Browse Source 
Added an `IsBuilt` property and `EnsureNotBuilt()` helper to `Factory` class
to restrict modifications to the service collection once the service provider
has been built. This ensures immutability and prevents runtime inconsistencies
after initialization.
