Removed:
- Extensive LaTeX configuration (~300 lines) - not used in this repo
- Excessive JetBrains IDE rules - simplified to essential only
- CMake, Gradle, Maven configs - not applicable
- Android, JIRA, Crashlytics configs - not relevant
Kept only what's relevant:
- IDE ignores (JetBrains, VS Code)
- Python artifacts (for Tools/ directory)
- OS-specific files (macOS, Windows)
- Common temporary files and logs
Reduced from 388 lines to 32 lines.
