cli-v0.17.0

Based on the commit messages, here are the release notes:

What's New

• Textbox editing — Edit text content inside VML and DrawingML textboxes with full interaction support; clicks map to content positions.
• Font family combobox — Browse and select fonts directly from the toolbar.
• Font size options — UI API exposes font size choices for custom toolbars.
• Comments API expansion — ui.comments.setActive() highlights a comment without scrolling; pending-comments-update event carries pendingSelection.
• Viewport scroll container — ui.viewport.getScrollContainer() returns the editor's resolved scroll element.
• Text range viewport geometry — ui.viewport.getRect() now accepts Document API text addresses and targets.
• Sidebar viewport observation — ui.viewport.observe fires when comments rail opens or closes.
• Zoom modes — Manual and fit-width zoom with observable transitions, viewport metrics, useSuperDocZoom React hook, and toolbar command.
• Table of contents hover — Hovering TOC entries highlights corresponding sections.

Improvements

• Multi-column section balancing — Continuous sections balance correctly with explicit per-column widths preserved throughout layout.
• Column spacing precision — Per-column gaps drive separator positions per ECMA-376; unequal-width columns honor per-column w:space.
• Font substitutes — Metric-compatible fallbacks load for Calibri, Cambria, Arial, Times New Roman, and Courier New before measurement.
• Tracked table changes — Inline cell edits consolidate into single review items instead of separate entries.

Fixes

• Paragraphs with pageBreakBefore style no longer add blank pages when directly following explicit page breaks.
• Textbox text alignment matches Word when tables are inside textboxes.
• Table cell selection highlights appear over empty space; multiline selection interior lines render at full width.
• Plan engine recovers from stale block identities on recompile without crashes.
• Tab carets anchor to line top instead of bottom; soft-break continuation carets position alignment-aware at line start.
• DOCX export preserves generated line breaks as <w:br/> elements instead of raw newlines.
• Font toolbar no longer races on editor handoff; combobox selection flow handles edge cases.
• Viewport geometry invalidates on sidebar toggle without px-level jitter.
• Zoom state — PDF documents contribute to viewport metrics; mode-only transitions emit correctly.
• TOC anchor navigation preserves bookmark start/end order.
• Image alpha modifiers process correctly on import and export.
• Font picker keyboard behavior consistent across selection modes.
• Formatting preserved when typing text over toolbar font selections.
