📄 Description

Summary

The Windows release was missing Tesseract OCR runtime dependencies (tessdata files) needed for the HardSubx feature to work. Users had to manually install Tesseract OCR and set TESSDATA_PREFIX environment variable.

This PR fixes that by:

Adding get_executable_directory() to ocr.c that finds the directory where CCExtractor is installed (works on Windows, Linux, and macOS)
Updating probe_tessdata_location() to search for tessdata in the executable directory, enabling bundled tessdata to be found automatically
Updating release workflow to download eng.traineddata and osd.traineddata from tesseract-ocr/tessdata_fast during release builds
Updating WiX installer to include the tessdata/ directory with the traineddata files

Now the Windows release includes tessdata files, and CCExtractor will automatically find them in the installation directory without requiring users to install Tesseract separately or set environment variables.

Test plan

Created test release on fork: https://github.com/cfsmp3/ccextractor/releases/tag/v0.97.0-test-tessdata
Verified portable ZIP contains tessdata/eng.traineddata and tessdata/osd.traineddata
Tested on Windows VM - HardSubx works out of the box without Tesseract installation

Fixes #1578
