chore(react): 1.9.0 [skip ci]

Perfect! I can see the release summary in the commit message. Let me refine it to match the SuperDoc voice and terminology:

### What's New

- **Content control navigation** — `ui.contentControls.focus()` places the caret inside a control; `ui.contentControls.scrollIntoView()` scrolls to it
- **Viewport geometry signal** — `ui.viewport.observe` emits when layout, zoom, scroll, or resize changes (single rAF-coalesced notification)
- **Content control events** — `content-control:active-change` and `content-control:click` include full activation stack and source detection (pointer vs. keyboard)
- **Content control chrome control** — `modules.contentControls.chrome` option suppresses visual styling for custom UI
- **Empty content control placeholders** — Inline and block controls display "Click or tap here to enter text" with inherited paragraph styling
- **Smart tags** — `w:smartTag` elements render and round-trip with visible content
- **Overlapping tracked changes** — Multiple tracked changes can occupy the same range in collaboration
- **Metadata orphan status** — Anchored metadata now reports an orphan status

### Improvements

- Find navigation no longer re-centers matches already on-screen
- Find navigation stops jumping when focus returns to search input
- Content control navigation skips hidden markers and atoms
- Content control labels anchor to the leading edge for visual consistency
- Block content control chrome extends across full fragment width
- Inline images top-align with text at baseline
- Block content control backgrounds no longer interfere with hover and click
- Inline content control wrappers with images size correctly to content
- Empty block content control paragraphs inherit surrounding text styles
- RTL content control chrome uses logical positioning
- Paragraph rendering unified between body and table cells
- Image helpers unified across all rendering surfaces

### Fixes

- Copy-pasted text in suggestion mode no longer reverts
- Block content control deletion respects lock modes
- Inline content control boundaries handle Delete correctly
- Backspace at inline content control boundaries selects content without chrome
- Cell-level content controls import, export, and preserve correctly
- Vertical merge cells inside content controls mark correctly
- Cross-editor diff application works (session-local attributes stripped from fingerprint)
- Undo/redo works inside content-locked controls
- Text-align remains visible in locked content control paragraphs
- Image data URIs validated before rendering or export
- SVG data URIs work without base64 encoding
- Nested table content controls preserve chrome across fragments
- Pointer-source tracking works on all editor initialization paths
