  • refactor(provider)!: collapse SingletonProvider/DecoratorProvider into Provider (#75) (9053f2a)

BREAKING CHANGES

  • SingletonProvider, DecoratorProvider, and
    ProviderDecorator are removed. IProvider.pipe() is removed; use
    the dedicated mutator methods. IProvider.addArgs() is removed; use
    addArgsFn() or the appendArgs(...) pipe. ScopeAccessOptions now
    includes args.

  • refactor(provider): move ProviderPipe into registration module

ProviderPipe only existed to bridge providers and registrations, and
registerPipe was only called from Registration.pipe. Co-locating it
with IRegistration makes the dependency flow one-directional and
removes the dedicated bridge file in lib/provider/.

  • refactor(provider): relocate inject helpers and pipe helpers to their owning modules

Fold inject/args/argsFn/resolveArgs into MetadataInjector — they exist
solely to support metadata-based reflection injection, so the file
that owns the strategy now owns the helpers.

Move appendArgs, appendArgsFn, scopeAccess, lazy, decorate, singleton
from IProvider into IRegistration, alongside bindTo and scope. Pipes
are a registration-layer concern (see prior commit relocating
ProviderPipe), so the helpers that produce them belong with the
registration module too. IProvider.ts is now purely the provider
type/interface.

Re-group lib/index.ts so the new locations sit with their existing
companions instead of as trailing one-liners.

  • feat(provider): throw CannonSingletonApplyError on duplicate singleton application

Add a strict guard: Provider.singleton() throws CannonSingletonApplyError
when called on a provider that already has a singleton configured. This
catches the silent-overwrite foot-gun where stacked pipes would let the
second call replace the first cache strategy with no observable error.

Also:

  • Remove the unused IMapper interface (dead code).
  • Refresh ADR 0004 to reflect the collapsed Provider class, the
    one-way provider→registration dependency, and the new error.
  • Drop the redundant @register(singleton()) decorator in Scopes.spec
    exposed by the new guard.
  • Rename the appendArgsFn+appendArgs test to make the chain semantics
    explicit (regression coverage for the appendArgsFn append fix).
