Read the current file sink snapshot from a `ConfiguredLogger`. This helper exposes path, availability, policy flags, rotation config, and failure counters as one object.

`file_state()` is the compatibility form. For truthful file-semantics detection, prefer `file_state_or_none()`.

- File-backed sinks return a live snapshot of file state.

- Queued file sinks forward the snapshot from the wrapped inner file sink.
|

- Non-file sinks return the same fallback empty-style state produced by `RuntimeSink::file_state()`, with an empty path, disabled policy flags, no rotation, and zeroed counters.

- This fallback keeps older callers source-compatible, but it is not a live file-backed snapshot.

- New diagnostic or recovery code should prefer `file_state_or_none()`.

- This helper is broader than individual file counters or policy accessors because it aggregates core file status into one read.

1. Use this helper for the main one-shot file status snapshot.
