ChuckandClaude Opus 5.5 7804ea8f69 feat(update): stable/beta update channel; stable follows release tags (#684 )

Adds auto_update.channel: stable follows the newest vX.Y.Z release tag
(detached HEAD; pre-releases and other tags ignored), beta follows main as
before. Nothing ever moves a device backwards: a checkout newer than the
newest release keeps following main (or stays put when detached) until a
release contains its commit. Legacy configs migrate to stable when they
reach a release. Update Code, the weekly updater's preflight, and the
verifier's rollback (back to old_ref: branch or detached release) all
honour the channel. General tab Update Channel select, GET/POST
/api/v3/system/update-channel, release-aware Overview banner and Tools git
panel. New installs default to stable.

Rig fix (ledpi): /system/check-update reports update_available: false when
the channel's action is none (a detached HEAD newer than the newest
release), matching Update Code; the Tools panel no longer calls every
detached HEAD "a release".

Merged with main through #687 (heartbeat verifier, #683 login, #688
plugin_catalog, #685 Tailwind build).

Utility Scripts

This directory contains utility scripts for maintenance and system operations.

Scripts

clear_cache.py - Clears LEDMatrix cache data (specific keys or all cache)
start_web_conditionally.py - Conditionally starts the web interface based on config settings
wifi_monitor_daemon.py - Background daemon that monitors WiFi/Ethernet connection and manages access point mode
pixlet_config_editor.sh - Opens Pixlet's own config UI for one installed Starlark app
apply_dns_single_request.sh - Adds options single-request to the resolver (run by ledmatrix-dns-fix.service)
auto_update_verify.py - Health check after an automatic update, rolling back if it fails (the updater copies it to data/ before pulling and ledmatrix-update-verify.service runs that copy)

Usage

Clear Cache

python3 scripts/utils/clear_cache.py --list          # List cache keys
python3 scripts/utils/clear_cache.py --clear-all      # Clear all cache
python3 scripts/utils/clear_cache.py --clear <key>    # Clear specific key

Start Web Interface Conditionally

This script is typically called by the systemd service (ledmatrix-web.service) and checks the web_display_autostart setting in config/config.json before starting the web interface.

WiFi Monitor Daemon

This daemon is typically run as a systemd service (ledmatrix-wifi-monitor.service) and automatically manages WiFi access point mode based on network connectivity.

Pixlet Config Editor

Run it when you want Pixlet's own config form for a Starlark app -- live render preview, cascading dropdowns -- rather than the LEDMatrix one.

./scripts/utils/pixlet_config_editor.sh                 # list installed apps
./scripts/utils/pixlet_config_editor.sh penndot_signs   # edit, on localhost:8080

Deliberately not a service. It stops the display for the length of the session and pixlet serve listens with no authentication, so it should only be running while you are actually editing. It backs the config up first and restarts the display on exit, however it exits.

It binds loopback only, with no flag to change that: anything that can reach pixlet serve can rewrite the app's config, and a printed warning is not access control. To edit from another machine, forward the port -- SSH does the authenticating and nothing is left listening on the LAN:

ssh -L 8080:localhost:8080 pi@ledpi.local

Apply DNS Single-Request Fix

Installed and run by ledmatrix-dns-fix.service; see systemd/README.md. Safe to run by hand (sudo ./scripts/utils/apply_dns_single_request.sh) and idempotent.
