AI Summary

This release focuses on improving PDF text geometry handling, including enhanced superscript and subscript support, alongside various performance and stability improvements for PDF loading and processing.

Key Highlights

Enhanced text geometry with support for superscripts, subscripts, and baseline metadata.
Improved PDF loading performance and robustness through bounded object-stream decompression.
New metadata handling for rotated text bounds and embedded bold fonts.
Faster cross-platform CI and release publishing processes.
Fixes for classic cross-reference tables to improve PDF parsing reliability.

Breaking Changes

Positioned items and region APIs now use the visible page box instead of manual CropBox-origin adjustments.
Rust `TextItem` literals must now include `baseline_shift`, `rotation`, and `advance_known` fields.

New Features

Password-aware Python fixture tests.
Python binding tests in CI.
Positions and regions relative to the visible page box.
Repair of classic cross-reference tables.

## Migration

- Positioned items and region APIs now use the visible page box. Remove any manual CropBox-origin adjustment; positioned items use a lower-left origin, while region inputs use a top-left origin.
- Rust `TextItem` literals must add `baseline_shift`, `rotation`, and `advance_known` (`0.0`, `0.0`, and `true` for ordinary upright text).
