HashHarvest v0.6.0

Added

• Full source file path is now shown as a tooltip on hover over the Source File column, so elided paths remain readable (main.py)

Changed

• Version bumped to v0.6.0 in the GUI version label and window title (main.py), with the window-title test updated to match (test_main.py)
• Results table columns are all user-resizable (Interactive) with sensible default widths; the last column stretches to fill leftover space (main.py)
• Results table now elides long text in the middle (ElideMiddle) so the drive root and filename of a path stay visible when a column is narrow (main.py)
• README documents the new .docx/.xlsx/.pptx parsing (file-types table and scope notes), notes that Office parsing adds no runtime dependencies, adds requirements-dev.txt install instructions, and corrects the SUPPORTED_EXTENSIONS example (README.md)
