Merge storytold/pdfcraft main into feat/lock-signatures-prompt

Conflicts:
- crates/ui-egui/src/workflows/js_ui.rs: main moved the Preferences dialog to
  crates/ui-egui/src/dialogs/preferences.rs (cards with search). Took main's re-export and
  carried this branch's "Otherwise, ask on the first save after a signature is placed"
  checkbox into card_fill_and_sign, disabled while flattening is on as before.

Done since (#1116): editable text regions grouped across compatible words and subset fonts, one rich-text editor over a background with the source text removed, embedded sfnt faces reused as editor faces, and visible (clipped) bounds for cropped-image selection and resize. Exclusive crops now resize across nested states and content streams, with shared clips fixed.<br>Done since: #594 ordinary paragraph drags preserve overlapping source text; UI/engine regressions, native save/reopen, independent-reader checks and full CI passed in the Linux test environment. #1200 candidate: local GoToR links open in desktop tabs and through root-confined automation; appearance-only edits preserve existing actions. Named destinations remain unapplied and `/NewWindow` is a tab hint. Done since: #3187: Added-image automation normalizes extreme signed rotation angles before combining them with the current orientation; integer bounds, history, pixels, save/reopen and MCP have regressions. Done since: #2592: Styled fallback fonts batch up to 240 glyphs per actual face and retain source styles. Budget refusal and distinct same-BaseFont descriptor weights have mutation-checked regressions; coverage and complex mixed runs remain limited. Missing: editing existing text and images in place (the longest pole), image/PDF watermarks PR #2155 candidate: editor-owned crops preserve original clips through group moves; Arrange preserves added-item stream ownership and refuses unsafe scope/state/tag extraction; image handles and flips follow page orientation; general transforms and Unicode script toggles have headless tools. Clipboard, mixed-size formatting, Home pins and reloadable installed-font discovery have review regressions. Latest follow-up uses explicit image-paste events, refreshes the mixed-size display, and documents script normalization with Undo. Further review covers inherited Form text and mask chronology, scoped transform composition, affine resize/rotation pivots, paste/selection ownership, no-op scripts and page-menu permissions. |
