Clip Pocket 0.5.1

Highlights

• Refined the work-tray export flow with grouped Selected snippets / Current session menus and added Copy selected as Markdown note.
• Improved Markdown note and GitHub issue draft output so exported text is easier to edit right away.
• Split more responsibilities out of ui.py and win32_host.py into dedicated modules for styling, settings-dialog construction, Win32 input tracking, tray helpers, and export action metadata.

Validation

• python -m unittest discover -s tests -v
• python -m py_compile src/clip_pocket/*.py tools/build_exe.py
