This release promotes the v0.7.2 development line (467 commits) to a public SDK release. The headline is a near-complete rebuild of the charting system, alongside major XLSX import fidelity work, a range of editing/interaction fixes, and public-repo hardening.

Primary PR: #11 — Release v0.7.2: charting system rebuild, XLSX import fidelity, public-repo hardening

📊 Charts — rebuilt from a broken baseline

Charting was effectively non-functional prior to this line; this is a ground-up rebuild of import, layout, and rendering:

• Combo charts: working value axes and dual-axis handling
• Doughnut: correct label and slice alignment
• Stacked areas: correct legend colors
• Axis handling: title placement at crossings, value-axis domain precedence
• Imported charts: aligned clustered-bar slots, correct single-series category semantics, preserved entry-driven legends
• API: charts.update no longer drops series updates

📥 XLSX / OOXML import durability

• Durable cell identity for floating-object anchors; per-sheet floating-object order persisted
• Deferred hydration for data-table regions, with viewport refresh and barrier promotion
• Active-sheet persistence deferred until import durability settles
• Fixed OOXML type-declaration emit boundary

🖱️ Editing & interaction fixes

• Editing of dynamic-array spill members
• Pivot: relocate output on cut-paste; imported layout reflected in field-panel wells
• Active cell kept at deletion index after row/column delete
• Cross-sheet clipboard paste routed through engine copy_range; paste values across sheets
• Threaded comments via right-click New Comment; fixed infinite recursion in comment normalization
• Content-aware responsive ribbon collapse (fixes Formulas tab clipping)
• Corrected Home keytips and Increase/Decrease Decimal stepping on General-format cells

🔒 Public-repo hardening

• Added a private-leak gate and scrubbed test fixtures / corpus provenance
• Refreshed contributing guidance and docs; applied rustfmt + prettier across the tree
