v0.4.4

What's New

Reliability Fixes

A targeted fix for spreadsheet handling that eliminates a frustrating save/reload behavior on file open.

• Spreadsheet refresh loop resolved — CSV and XLSX files no longer get stuck in a save-then-reload cycle when opened. The tab stays clean and stable instead of cycling through dirty/saving states.
• No more phantom dirty state — clicking around cells or scrolling within a spreadsheet no longer marks the tab as modified when you haven't actually changed anything.

Improvements

• Added LICENSE, SECURITY, and CONTRIBUTING documents to the repository for clearer project governance and contribution guidelines.
