feat: Linux bulk importer for the Allflame Voyage Solver

Mirrors the solver's Windows-only voyage-import.ahk on KDE Wayland:

- poe-clip-bridge.py: clipboard watcher that keeps only PoE item text,
  serves it on loopback and can trigger a sweep from the browser
- voyage-sweep.py: hovers every cell of the in-game chart grid, Ctrl+C's
  it and hands over the whole batch in one go
- userscript: feeds the batch into the solver page without focusing it

Includes notes on the four Wayland pointer pitfalls this ran into.
