This commit updates the README files for the `core:api`, `core:model`, and `core:proto` modules to improve documentation and reflect current usage.
Key changes include:
- Bumping the library version to `v2.7.13` in usage examples.
- Adding a detailed README for the `core:proto` module.
- Updating the `core:api` README to use `MeshtasticIntent` constants instead of hardcoded strings.

This commit centralizes all Android Intent constants into a new `MeshtasticIntent` object within the `core/api` module.
This refactoring makes the constants accessible to external applications and removes the duplicated definitions from the main application. The app and the service example have been updated to use these new centralized constants.
