Description

I have made some attempts at shipping the Python plugin in the snap, but the simply approach of building against Python and then relying on the system Python at runtime doesn't work (like it does for the AppImage):

https://github.com/bjorn/tiled/blob/9df61be40c061289cb842f5709adbf6b9ec1e8a2/snap/snapcraft.yaml#L42-L44

Probably we need to ship a complete Python runtime environment rather than trying to rely on a system-installed Python on the user's side.

Shipping a Python runtime would also fix compatibility issues we're currently having if the system Python version is different from the one Tiled was compiled against (those issues also affect the AppImage and the Windows installer package).

Research direction
Investigate the current snapcraft.yaml at the linked commit to understand the failed approach. Look into bundling a complete Python runtime (e.g., using snap Python content interface) to avoid relying on system Python. Check how other snaps ship Python plugins for inspiration. Consider testing compatibility with different Python versions.
