chore(examples): remove outdated example binaries from the repository

- Deleted several example binaries, including `farp-auto-detection`, `runnable-extension-demo`, `ai-demo`, `security-auto-middleware`, and `basic` from the `farp` directory, to declutter the codebase and remove unused resources.
- Updated `.gitignore` to reflect the removal of these binaries, ensuring they are no longer tracked.
