v0.9.0 promotes the unified SDK runtime line with stronger chart export, import hydration, and spreadsheet correctness work.

Primary PR: #28 - Release v0.8.2: chart fidelity, import hydration, SDK runtimes

SDK Runtime

• Unified SDK package — @mog-sdk/sdk replaces the old Node-only package name and adds package-root runtime conditions plus explicit ./node, ./wasm, and ./workerd entries.
• Runtime packaging — Node, WASM, and workerd-style hosts now share stronger bootstrap behavior and publish verification across SDK-owned runtime dependencies.

Charts And Export

• Chart fidelity — deeper Excel chart geometry support across Cartesian, pie/doughnut, radar, stock, scatter/bubble, combo, treemap, and related chart families.
• Chart image export — multi-runtime SVG/raster export support with stricter chart diagnostics, semantic legends, rendered-series snapshots, and color/geometry authority checks.

Import And Data Features

• XLSX import hydration — deferred imports now materialize at the right editing/export boundaries while avoiding passive-read materialization.
• Pivots and filters — imported pivots and AutoFilters now hydrate into native runtime structures with stable identities, diagnostics, placement editing, and row-visibility provenance.

Spreadsheet Behavior

• Editing and navigation fixes — improved typed input preservation, spill-child edit guards, validation dropdown reopening, page/Home alignment, range-picker keys, and selected-border navigation.
• Formula and compute correctness — restored circular-reference behavior, improved iterative convergence, and fixed structured-reference rewrites, formula text preservation, and lifecycle named-range refresh.
