Summary

This PR adds continuous slide quality analysis while editing, Mermaid diagram rendering in previews and exports, and export quality gating — plus presenter and preview improvements that landed on the same branch.

Slide quality

Live analyser (SlideQualityAnalyzer) checks contrast (body, title, table, code, accent, footer, checklist, section), alt text / media descriptions, missing image/video files on disk, and text density (bullets, tables, code, markdown, title, quote).
Quality bar below the preview with severity filters; thumbnail badges and inline editor hints.
Click an issue to jump to the slide field or open Settings → Colours with the matching theme colour highlighted.
Export dialog: soft warning (Warn on export) and optional hard block (Block export on serious quality issues). Policy strings are fully localised.

Mermaid

New MermaidRenderService and MermaidDiagram widget; diagrams render in slide preview, presenter, and raster/PDF/PPTX/HTML export paths.

Other

Presenter / dual-screen and table preview refinements.
Platform feature flags for web vs desktop; documentation updates (USER_GUIDE, CHANGELOG, architecture/build notes).
415 tests — make check green.

Test plan

make check
Low-contrast theme → deck-wide issues; click → Settings opens on highlighted colour
Dense slide / missing alt text → click issue → jumps to slide and focuses editor field
Export with warnings/errors → confirm dialog; with block setting → errors refuse export
Mermaid fenced block → visible in preview, presenter, and exports
Presenter on second display still syncs; table/chart previews unchanged for existing decks

feat: slide quality analysis, mermaid rendering, and export quality gating b19660fefc

Add a slide quality analyzer with a quality panel and details dialog, a
deck quality provider, and quality localization; gate and annotate exports via
a quality export policy and export metadata.

Add a Mermaid diagram rendering service and widget, plus markdown
validation, colour-contrast (accessibility) helpers, slide rasterizer and
preview refinements, and a new platform layer.

Docs updated (architecture, build, file format, shortcuts, user guide).

Note: working tree captured as-is; lib/l10n/app_localizations.dart has a
duplicate const-map key that currently breaks the build.

Extend slide quality with field navigation, accent contrast, and export l10n.
