feat: various UI fixes, prompt optimizations, and allowing duplicate docs

- Updated `content_hash` in the `Document` model to remove global uniqueness, allowing identical content across different paths.
- Enhanced `_create_document` function to handle path uniqueness and prevent session-poisoning from `IntegrityError`.
- Added detailed comments for clarity on the changes and their implications.
- Introduced new citation handling in the editor for improved user experience with citation jumps.
- Updated package dependencies in the frontend for better functionality.

+/**
+ * Citation-jump highlighter. Re-uses Plate's built-in `FindReplacePlugin`
+ * (decorate-only, no editing surface) to drive the "scroll-to-cited-text"
+ * UX in `EditorPanelContent`. We register it in every preset because:
+ *   - Decorate is a no-op when `search` is empty (single getOptions() check
+ *     per block), so cost is effectively zero for non-citation viewers.
+ *   - Keeping it preset-agnostic means citations work whether the doc is
+ *     opened in editable (`full`) or pure-viewer (`readonly`) modes.
+ *
+ * The parent component drives `setOption(FindReplacePlugin, 'search', ...)`
+ * + `editor.api.redecorate()` to trigger highlights, then queries the
+ * editor DOM for `.citation-highlight-leaf` to scroll the first match
+ * into view. (We can't use a `data-*` attribute here — Plate's
+ * `PlateLeaf` runs props through `useNodeAttributes`, which only forwards
+ * `attributes`, `className`, `ref`, `style`; arbitrary `data-*` props are
+ * silently dropped.) See `components/ui/search-highlight-node.tsx` for
+ * the leaf component and `CITATION_HIGHLIGHT_CLASS` constant.
