Update tesseract-rs requirement from 0.1 to 0.2 in /ext/parsekit

[dependabot]

Updates the requirements on tesseract-rs to permit the latest version.

Release notes

Sourced from tesseract-rs's releases.

v0.2.0 — Memory Safety & Robustness Release

Critical Fixes

• Use-after-free in process_pages() CString handling
• Undefined behavior in detect_os() freeing Tesseract's static pointer
• Unsafe transmute replaced with safe from_int() enum conversions
• Memory leak in get_word_confidences() (never freed C array)
• ChoiceIterator incorrectly freed internal Tesseract pointer

Breaking Changes

• Clone removed from TesseractAPI → use try_clone() (fallible)
• MutableIterator removed (was dead duplicate of ResultIterator)
• PageIterator, TessMonitor, TessResultRenderer methods now return Result<T>
• is_valid_word() returns Result<bool> instead of Result<i32>
• MutexError variant removed → use MutexLockError

Added

• try_clone() — fallible clone for TesseractAPI
• ResultIterator::get_choice_iterator() — access alternative recognition choices
• 4 enum types re-exported: TessOrientation, TessWritingDirection, TessTextlineOrder, TessParagraphJustification
• 179 tests (up from 14) — 91.6% code coverage
• End-to-end test scenarios simulating real-world usage

[0.2.0] - 2026-03-23

BREAKING CHANGES

• Removed Clone impl for TesseractAPI — use try_clone() instead
• Removed MutableIterator type from public API
• Removed duplicate analyze_layout() — use analyse_layout() (matches C API)
• Removed get_mutable_iterator() — use get_iterator()
• Changed is_valid_word() return type from Result<i32> to Result<bool>
• Changed PageIterator methods to return Result<T> instead of bare types
• Changed TessMonitor methods to return Result<T> instead of bare types
• Changed TessResultRenderer methods to return Result<T> instead of bare types
• Removed duplicate MutexError variant — use MutexLockError
• Deprecated get_word_confidences() — use all_word_confidences()

Fixed

• Critical: Use-after-free in process_pages() CString handling
• Critical: Undefined behavior in detect_os() freeing Tesseract's static pointer
• Critical: Unsafe transmute replaced with safe from_int() enum conversions
• Critical: Memory leak in get_word_confidences() (never called TessDeleteIntArray)
• Critical: ChoiceIterator incorrectly freed internal Tesseract pointer via TessDeleteText
• Fixed print_variables_to_file() inverted success/error logic
• Fixed get_unichar() panicking on mutex lock failure
• Fixed inconsistent mutex error handling (some modules panicked, others returned errors)
• Fixed Drop implementations to use if let Ok() pattern (no panic on poisoned mutex)
• Fixed null pointer comparison using == instead of .is_null()

Added

• TesseractAPI::try_clone() — fallible clone that returns Result
• ResultIterator::get_choice_iterator() — access alternative recognition choices
• Re-exported TessOrientation, TessWritingDirection, TessTextlineOrder, TessParagraphJustification
• Consistent #[cfg(feature = "build-tesseract")] on all extern blocks
• 179 tests (from 14) covering all modules with 91.6% coverage
• End-to-end tests simulating real-world usage scenarios
• Shared test helpers module

Removed

• src/mutable_iterator.rs — was a complete duplicate of ResultIterator
• Unnecessary clippy allow attributes

[0.1.20] - 2025-07-27

Added

• Comprehensive unit tests for error handling and enums
• Benchmark tests using criterion
• Code coverage reporting with tarpaulin
• Commit message standards (Conventional Commits)
• Pre-commit hooks with Husky for code quality
• CI/CD pipeline with clippy, rustfmt, and security audit
• Contributing guidelines
