ISTTEngine.hpp and ISTTService.hpp both defined TranscriptionCallback with different signatures: - ISTTEngine: void(const std::string& text) - ISTTService: void(const std::string& text, STTMode mode) This caused compilation errors due to conflicting declarations. Solution: Rename the low-level engine callback to STTEngineCallback to distinguish it from the high-level service callback. Fixes: Compilation errors in Phase 7.1 STT Service Layer - All 120 unit tests passing (282 assertions) - Build successful 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
