kjump 0.1.0 — run-or-raise for KDE Plasma 6

First public release. Run-or-raise for KDE Plasma 6 (Wayland and X11):
press a global shortcut to focus a matching window, or launch the app if
none is open.

Added

• kjumpd daemon: registers a global shortcut per app via kglobalaccel,
  raises matching windows through KWin's scripting D-Bus, and launches the
  configured command when no window matches. Owns its own kglobalaccel
  component, so all bindings appear as a single KJump section in
  System Settings → Shortcuts, persistent across daemon restarts.
• Bidirectional shortcut sync: edits in the GUI push to kglobalaccel, and
  edits made in System Settings sync back into apps.json.
• kjump-config GUI (PySide6): manage apps and shortcuts, pick from
  installed applications, and grab a window's class with Pick from
  window….
• kjump <entry> CLI: trigger run-or-raise from the command line by an
  entry's id or name (case-insensitive) — for scripting and automation
  without binding a global shortcut.
• --version on kjumpd, kjump-config, and kjump.
• Per-user make install / make uninstall (to ~/.local, no root),
  including a systemd user unit for the daemon and a dependency check.
• MIT license.

Notes

• The Qt 6 qdbus CLI the GUI shells out to is named qdbus-qt6 on
  Fedora/Debian and qdbus6 on Arch; kjump-config resolves whichever
  is present.
