feat(platform): Add support for APFEL as part of the dependencies and models for the Cookbook. (#2657)

* feat(platform): add support for Apple Silicon detection in platform compatibility

test(tests): enhance shell_routes tests for Apple Silicon compatibility

* fix issues with missing import

* fix: correct package name in package-lock.json and enhance package installation commands in shell_routes.py and cookbook.js

* feat: add Apfel startup and health checks on macOS

- bootstrap Apfel via Homebrew on arm64 macOS
- start `apfel --serve --port 11435` detached for Odysseus
- verify readiness via `/health`
- clean up the Apfel process on exit or Ctrl+C

* fix: duplicate variable declaration post-merge conflict
- Should fix `node` CI issues.

* fix: issues with the update status of the APFEL dependency.
- fixed by changing the main conditional that determines the update.

* Fix: Remove unnecessary whitespaces and formatting for the model_routes.py file.

* Fix: whitespace issues with the model_routes file

* Fix: Remove unnecessary whitespaces and formatting for the model_routes.py file. Final

* Fix: Fixed updates using PIP for APFEL instead of custom cmd
