API Stability

Some notes on what parts of festivald's API can/cannot be relied upon.

In general - things may be added, but never removed.

If something is unstable, it will be marked as such.

Anything that feels like an API but isn't explicitly marked in festivald's documentation should be assumed to be 🔴 Unstable.

Breaking Changes

Breaking changes to the stable API may occur in 3 situations:

1. festivald v2.0.0 release
2. There is a fundamental/security bug that must be fixed in festivald
3. There is a difference between this documentation and the actual festivald input/output

These will be noted in release notes if they ever occur.
