Library update (#78)

* Added print functionality to PDF viewer

* feat(pdf): add interactive button support and visibility reveal heuristic

* Moved search state management to MainViewModel and improved search UI interaction.

* Updated `pdfiumandroid` to version 2.0.0 and handled resulting API changes, including nullable page/text page returns and revised native pointer access.

increased compileSdk to 36.

* Fixed Table of Contents (TOC) truncation bug and improved the TOC UI in `PdfViewerScreen`.

- Implemented `getFixedTableOfContents` using reflection to bypass a library issue where sibling nodes were incorrectly truncated during traversal.
- Enhanced the TOC drawer with a nested, expandable tree structure using the new `PdfTocTreeItem` component.
- Added a custom `VerticalScrollbar` with draggable support for better navigation within long TOC lists.
- Integrated `animateColorAsState` and `animateFloatAsState` for smoother UI transitions in the TOC and scrollbar.
- Optimized TOC loading by flattening the tree structure and managing expansion states with `rememberSaveable`.

* Improved zoom pivot calculation and interaction handling in PdfVerticalReader

* Fixed high-res PDF tile bleeding by implementing clipRect in PdfBitmapLayer

* fix(pdf): resolve zoom stuttering, in pagination mode, by removing eager scale snapping

* Added book pinning and library filtering functionality

* Updated folder sync logic, improved metadata extraction, and added persistent banner message while syncing

* build: bump version to 1.0.37 (38)
