RemoteINDIPAD v0.9.0 beta 8

Changelog

Added

• Added INDIPAD JSON protocol documentation and a JSON schema definition (docs/protocol.md, docs/protocol.schema.json).
• Added the GNU Lesser General Public License version 2.1 to the project.

Changed

• Migrated D-Bus integration from dbus-next to QtDBus, removing the dbus-next dependency and its license file.
• Replaced the pygame dependency with pygame-ce.
• Added a placeholder type for missing PySide6 classes so that using GUI features without PySide6 installed raises a clear error instead of behaving like a bare object.
• Removed deprecated per-instance Joystick.init() calls in the sender (pygame 2.4.0+ deprecation).
• Removed FOCUS_STOP and SKYMAP_MOVE from the action names list for clarity.
• Renamed pygame-LGPL-2.1.txt to pygame-ce-LGPL-2.1.txt.
• Updated build-pyinstaller.yml (Ubuntu runner version, target/job description clarity).
• Fixed the gamepad profiles configuration path used in test_default_mapping_uses_gamepad_profile_value.
• Updated the package version to 0.9.0b8.

Documentation

• Updated the README files to clarify wheel file installation/usage instructions and the QtDBus migration.
• Updated docs/DEVELOPMENT_POLICY.md for the QtDBus migration and LGPL-2.1 license.
