[Feature]: Native Decorator Metadata (Symbol.metadata) #20
Description
What problem would this feature solve?
Migrates from the legacy reflect-metadata library to the new standards-based decorator metadata protocol, reducing dependencies and aligning with ECMAScript/TypeScript best practices.
Proposed solution or design
Refactor all decorators and metadata access to use Symbol.metadata. Remove reflect-metadata as a dependency. Provide a migration path for users upgrading from older TypeScript versions.
Additional context
See the NexusDI Roadmap: Native Decorator Metadata (Symbol.metadata) for migration plan and API examples.
