feat: add `ago/2` query function
feat: add basic arithmetic operators (+, *, -, /)
feat: `sensitive?` option for attributes
feat: `sensitive?` option for arguments
feat: `private` arguments, which can’t be set using `for_<action>`
feat: add `prevent_change` which will erase changes just before the changeset is committed
feat: add `match?` validation that supports a custom error message
feat: add `interval` type to support `ago/2` function

improvement: `changing?` is now a validation
improvement: add `Transformer.get_persisted/3`
improvement: add `api` field to `Notification`
improvement: standardize errors, add `to_error_class`
improvement: use `Comp` everywhere
Improvement: use action on changeset if set by `for_<action_type>`
improvement: `action_failed?` field on change sets
improvement: remove ability for data layers to add operators (for now at least)
Improvement: Changeset.apply_attributes/2 now returns an error tuple
Improvement: add a bunch of new/informative errors
improvement: runtime filter now uses left join logic (a naive implementation of it)
improvement: support more filter templates in resources
Improvement: basic/naive type system for operators/functions
Fix: properly expand module aliases for options w/o compile time dependency
chore(engine): track changeset changes for the request with `manage_changeset?: true`
The delegation data layer was the wrong tactic. We should model
shared behavior as composition, not inheritance (which is essentially
what the delegation data layer turned into)
