Removes development scratch that belonged to the Windows port and has no
purpose on the Linux/Pi branch. 39 tracked files removed; everything is
recoverable from the Windows-Player branch.
Removed
-------
- working_files/ (29 files) - dev-era scratch: install.sh.bak, the superseded
get_playlists.py (v1, replaced by get_playlists_v2.py), one-off test_*.py
probes, MIGRATION_GUIDE.md, INVESTIGATION_RESULTS.md. Also held real server
captures (server_response_debug.json contained player_id, player name and a
playlist) which should not be in the repository at all.
- documentation/ (5 files) - all described the Windows-era HTTPS integration.
- "python version" - contained Python 3.12.9, the Windows build interpreter.
The Pi runs 3.13.5.
- test_edited_media_upload.py - parentless debug script, referenced by nothing.
- .display-keepalive.sh, .keep-screen-alive.sh, .wait-for-display.sh - orphan
X11 helpers referenced by nothing; superseded by linux/linux_display.py.
Kept deliberately
-----------------
- .video-optimization.sh, .run-background.sh, .start-player-cron.sh -
referenced by install.sh.
- repo/python-wheels/ (58 MB of aarch64 cp313 wheels) - the offline install set.
- .venv/ is gitignored; runtime caches (.kiosk-profile, .kivy), logs, media and
the playlist cache are regenerated automatically and stay ignored.
Also fixed a stale reference to the removed documentation/ directory in
linux/development-track.md, and recorded the above there.
Verified after removal: all modules under src/ import cleanly from an unrelated
working directory, all remaining shell scripts pass `bash -n`, and the running
player was unaffected (correct: it had already loaded its code).
