Bump tesseract-rs from 0.2.0 to 0.3.0 in /ext/parsekit

[dependabot]

Bumps tesseract-rs from 0.2.0 to 0.3.0.

Release notes

Sourced from tesseract-rs's releases.

v0.3.0

Highlights

Breaking

• MSRV raised to 1.88.
• get_int_variable() / get_bool_variable() / get_double_variable() now return the real value / Err, not the C BOOL flag.

Added

• FreeBSD support (build + tests in CI).
• embed-tessdata feature — single-binary deployment via init_embedded().

Changed

• Bundled Tesseract 5.5.2 + Leptonica 1.87.0 (C++17); all deps upgraded to latest.

Fixed

• SIGSEGV from truncated Init4/Init5 FFI signatures.
• Get{Int,Bool,Double}Variable FFI signatures (memory-unsafe getters).
• Windows debug static-library naming (#17).

Thanks to @​mwstowe (#20) and @​YageGeng (#25); historical: @​bombless (#2).

[0.3.0] - 2026-07-08

BREAKING CHANGES

• Raised the minimum supported Rust version (MSRV) to 1.88 (required by the upgraded dependencies).
• get_int_variable(), get_bool_variable() and get_double_variable() now return the actual variable value and Err(GetVariableError) when the variable is not found, instead of the C BOOL success flag.

Added

• FreeBSD support — the build and full test suite now run on FreeBSD in CI (via a FreeBSD VM).
• embed-tessdata feature: embed .traineddata directly into the compiled binary and load it at runtime with init_embedded() / embedded_languages().

Changed

• Upgraded the bundled Tesseract 5.3.4 → 5.5.2 and Leptonica 1.84.1 → 1.87.0, now compiled with C++17.
• Upgraded all dependencies to their latest versions (thiserror 2, reqwest 0.13, zip 7 deflate-only, imageproc 0.27, etc.).

Fixed

• Fixed a SIGSEGV caused by truncated TessBaseAPIInit4 / TessBaseAPIInit5 FFI signatures (missing trailing parameters).
• Fixed the TessBaseAPIGet{Int,Bool,Double}Variable FFI signatures (missing output pointer), which returned wrong values and could corrupt memory.
• Fixed the Windows debug build failing to locate the d-suffixed static libraries (#17).

Contributors

• FreeBSD support and the embed-tessdata feature were contributed by @​mwstowe (#20).
• The deflate-only zip configuration was contributed by @​YageGeng (#25).
• The Windows debug-library and C++17 build fixes were cross-checked against the maintained xberg-tesseract fork.
