feat(routes-f): pick and omit object keys

[davedumto]

Summary

Return an object with only picked keys, or with omitted keys removed.

Requirements

• POST { input: object, mode: pick|omit, keys: string[] }
• Support dot-paths for nested keys
• Return { result }
• Tests cover top-level and nested pick/omit

Scope Constraint - READ BEFORE STARTING

All files for this task must live inside app/api/routes-f/. This includes the route handler, helpers/utilities, types, and tests. Do NOT modify, import from, or add files to lib/, utils/, types/, components/, or anywhere else outside app/api/routes-f/. If you need shared logic, duplicate it inside your subfolder. Keeping everything scoped to this folder is intentional - it keeps these tasks independent and mergeable in any order.

Hi Maintainer, I’d like to implement the pick/omit routes in app/api/routes-f/ with support for nested dot-path keys, plus tests to ensure both modes behave correctly.
