feat: add 'function' support to fp-sdk's primitive type guards

[knocte]

fp-sdk has dynamic casting that works both for primitive types (string, int, boolean...) and also objects. However, function is not among the primitive types that are tested and/or implemented (yet).

/pi please work on this feature (repo: https://github.com/tarsgate/fp-sdk) you can push your work to a new branch at the fork of this repo on the nodefect github account ( https://github.com/nodefect/fp-sdk ). (The TOKEN you have available corresponds to this nodefect account actually.) After pushing there, then create PR from that branch.

Implemented and pushed the feature. Here's what was done:

• Updated src/dyn.ts: added FunctionConstructor to the conditional return types in both Dyn.cast().to() and Dyn.tryCast().to(), mapping it to Function alongside the existing String → string, Number → number, and Boolean → boolean primitive mappings.

• Updated src/fpSdk.test.ts: added three new test blocks covering:

  • Dyn.cast(value).to(Function) with arrow functions, regular functions, Function constructor instances, and negative cases (string, object, number)
  • Explicit type assignment (Option<Function>)
  • Dyn.tryCast(value).to(Function) including nullish inputs

All 14 tests pass (npm test ✅).

• Pushed to fork: branch feat/function-type-guard on nodefect/fp-sdk
• Created PR: feat: add 'function' support to fp-sdk's primitive type guards fp-sdk#24
