Full changelog

What's new

PDF form filling. Interactive PDF forms now render their fields (text inputs, checkboxes, radio buttons) as live controls. Fill them in directly and save — field values are written back into the PDF.

PDF outline (bookmark) navigation. A new OUTLINES tab in the sidebar displays the document's bookmark tree. Click any entry to jump to that page. The sidebar auto-fits its width to the longest entry on open and can be dragged wider; switching back to PAGES snaps to the pages-mode width.

Fixed

Page rotation no longer reverts after saving. Rotations applied via the sidebar context menu now persist correctly through the save pipeline.
Copied text words were out of order on PDFs where glyphs are stored in non-reading order (Issue #66). Text extraction now sorts words by position and uses a dynamic line-grouping threshold so both drag-select and Select All produce correctly ordered output.
PDFs with malformed or non-standard XRef tables now open in read-only mode instead of showing "Invalid entry in XRef table" and failing entirely.
