Dependency and scope

Draft, stacked on #1544. Keep this PR as a draft until A is merged, then rebase onto the resulting main so only the section rail and optional persistent grid remain in its diff.

Summary

Add a resizable, collapsible section rail beside the native presenter's current slide, next slide and notes. Opening or folding a section leaves the audience slide unchanged; picking a preview navigates to that slide. The rail supports one or two previews per row, highlights the current section, and truncates long names with a tooltip.

The divider resizes the rail up to a third of the window while preserving room for the slide and notes. Clicking the grip hides or restores it. Only visible previews remain cached, with bounded texture dimensions and per-frame rendering work; folding or hiding the rail frees its previews.

This PR introduces Keep All slides open, moved out of #1544. It defaults off: selecting a native thumbnail by click or Enter closes the grid. When enabled, selection preserves the grid. Disabling it closes the grid while preserving expanded rail sections. Escape, G and presenter-window close still dismiss the grid. The remote web presenter is unchanged.

The rail and persistence option are DeckCraft additions; they do not increase PowerPoint parity scores. No document-model or file-format change. A's startup GPU fix and upstream asynchronous next-slide previews are preserved.

Validation

• All eight local CI stages passed: fmt, pdf-deps, Clippy, workspace tests, doctests, assets, layers and WASM.
• UI suite: 527 passed, 4 ignored. Includes rail navigation/layout/resize, persistence on/off, input-state identity, Enter/Escape, checkbox disable behavior, invalid dimensions and more than 48 visible rail previews with release on fold.
• Native Windows / DirectX 12 direct --show startup verified with 300 slides, Presenter View, G/Escape and normal shutdown.
• Contributor visual testing of the previous published build reported no observed issues after the startup fix.
• Restacked onto revised A e1bafbe and main 159ed07. All eight local CI gates ran on this final B source, including the bounded tab strip, removed-filter recovery and remote-popup keyboard regressions.
• Rebuilt native binary verified with 61 long sections at 1000 x 700: the last section retains a visible preview; removing all sections restores the complete grid. Normal exit 0.

Validated source: 200a231. Local validation is separate from GitHub CI and maintainer review; GitHub checks need to run on the updated branch. B remains a dependent draft.
