- Feature.register returns the config as a second value, so files
write `local feature, config = Feature.register(...)`.
- The lib is ExpScenario.Features and the instance class with its
fields sits on Feature._prototype, which is the __index, the same
shape as exp_commands.
- update_config only looks at values whose override was added,
removed, or replaced. _apply_field sets one value and returns it, so
the comparison happens while applying and the second loop only
raises. Overrides dropped from the previous set count as candidates
because the value reverts to its default.
- The `@setting name` tags are gone from the config comments.
- Protection is guarded as a whole instead of checking config.enabled
in one handler. The handlers also forget mined entities, so
get_entities and is_entity_protected now drop invalid references,
which also covers entities destroyed without an event. The list
getters are gone, the selection overlay builds its lists from
Protection.config.
- Chat and damage popups are one feature in control/popups.lua.
- ignore_admins and command_admin_only are removed, roles cover them.
