other landed components: replace `let mut` element variables reassigned landed components: `let mut` element variables reassigned under `if` /
under `if` / `if let` with one chained expression using `.when(...)` / `if let` now build one chained expression with `.when(...)` /
`.when_some(...)` / `.map(...)`. The sidebar row is the model; sweep `.when_some(...)` / `.map(...)`. Converted: Tabs strip root and tab,
`crates/core`, `crates/data`, `crates/editor`, `crates/layout`, and Menu / DropdownMenu / Popover / Combobox wrappers, ScrollArea pane and
re-run tests plus a gallery pass after each crate. scrollbars, Select rows, Dock tab entries, Resizable panes and dividers,
the Markdown text / code / table rows, and the Diff gutter cell.
`MenuItem` and `Tab` adopted `FluentBuilder` so their builders chain
too; data accumulators (`Vec`/`String` builders, style clones) stay
imperative — they are state, not element refinement.
