fix: support native array methods on collections

[Jannik-cmyk]

Summary

• make native Collection transforms return plain arrays through Symbol.species
• preserve the existing constructor and metadata invariants
• add regression tests for map, filter, and slice

Root cause

Native Array transforms use the subclass species constructor. They pass an array length, but Collection expects an iterable of models and spreads it into super(), causing the reported error. Returning Array from Symbol.species keeps Collection construction strict while making transforms return normal arrays.

Validation

• reproduced the old failure in a focused harness
• verified map, filter, and slice return plain arrays
• verified the source collection and metadata remain unchanged
• TypeScript transpilation checks
• git diff --check
• branch changes only the implementation, regression tests, and patch changeset

Fixes #874
