AI Summary: This issue requires persisting the runtime visibility state of `Layer` and `Level` data structures. Currently, this visibility property is not saved within the `io` crate, and the task is to ensure it is properly persisted.

AI Summary: This issue proposes conditionally deriving the `Reflect` trait for data structures within the `data` crate. This is necessary to enhance support for an inspector plugin, but only when the `dev` feature is enabled during compilation.

AI Summary: The CI tool's current implementation for extracting variables from Fluent translation files is incorrect. It misinterprets `{ $key }` as having an argument named `$key` instead of the correct `key`, requiring a fix to the parsing logic.
