egui now derives "no ui is shown this pass" from the `minimized` /
`occluded` flags the integrations already report in `ViewportInfo`,
instead of a new `RawInput` flag that they had to set separately.

Enable these new clippy lints and fix all warnings:
* `format_push_string` — use `write!` instead of `s += &format!(…)` to
avoid extra allocations
* `ignored_unit_patterns` — use `()` instead of `_` when matching unit
* `missing_fields_in_debug` — ensure manual `Debug` impls account for
all fields
* `needless_raw_string_hashes` — remove unnecessary `r#` on string
literals
* `ref_option` — prefer `Option<&T>` over `&Option<T>` in function
signatures
