Packaging rework (#531)

* fix: get rid of title view jank on latest beta

* Count the number of installs for each plugin (#557)

* Bump aiohttp from 3.8.4 to 3.8.5 in /backend (#558)

* fix: include Decky version in request for index.js

This avoids the If-Modified-Since logic in aiohttp and ensures Steam doesn't cache old JS,
even if the timestamps are normalized.

* fix: clean up shellcheck warnings in act runner script

* fix: gitignore settings/

* fix: ensure state directories exist when running without the installer

* feat: determine root directory correctly when running from in-tree

* fix: fix typo in CI script

* refactor: build a proper Python package with poetry

* refactor: move decky_plugin under the poetry structure

There's no need to special case it anymore, just treat it like any other Python module.

* sandboxed_plugin: better fix, attempt 2
