AI Summary

This release focuses on enhancing text geometry, improving superscript and subscript handling, and fixing PDF loading issues. It includes performance optimizations for CI and release processes, along with enhanced metadata extraction for rotated text and fonts.

Key Highlights

Enhanced text geometry with superscript/subscript support and baseline metadata.
Improved PDF loading with bounded object-stream decompression and cross-reference table repairs.
Added rotation metadata and embedded bold-font recovery capabilities.
Optimized CI and release publishing workflows.

Breaking Changes

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

New Features

Bounded object-stream decompression to prevent excessive memory usage.
Password-aware Python fixture tests for better security coverage.
Python binding tests integrated into the CI pipeline.
Support for rotated-text bounds and rotation metadata.
Embedded bold-font metadata recovery.
Repair functionality for classic cross-reference tables with short entries.

Full Release Notes

## 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).
