Full changelog

Mog SDK v0.9.1 strengthens API/runtime correctness, SDK compatibility metadata, XLSX parity, CLI release hardening, and spreadsheet interaction polish.

Primary PR: #30 — Promote dev-v0.9.1 to main

SDK APIs

Compatibility registry — adds public SDK API compatibility metadata and agent-facing API guidance artifacts.
Workbook and worksheet correctness — hardens stale handle behavior, pivot introspection, pivot metadata, blank visibility, range-backed queries, and API-authored TABLE formulas.

XLSX and Compute

Import/export parity — improves deferred hydration identity allocation, explicit blank export, imported autofill, and data table recalculation.

CLI and Release Flow

Trusted artifact publishing — updates SDK and CLI release plumbing so publish dry-runs and CLI packaging use the trusted SDK artifact flow.

Spreadsheet UX

Interaction polish — improves copy/fill formatting, paste-special overwrite behavior, platform-aware context menu shortcuts, and stale color picker selection state.
