Four small, independent improvements bundled into one cut:
1. Restrict device discovery to SoundTouch-family services (#269/#359).
- mDNS now queries all three SoundTouch service-type variants in
parallel (_soundtouch._tcp, _bose-soundtouch._tcp, _soundtouchstick._tcp)
and deduplicates results by host:port. mDNS has no native wildcard
for service types, so we fan out one query per variant.
- UPnP/SSDP M-SEARCH receives a manufacturer/modelName check after
fetching the device description: devices whose manufacturer doesn't
contain "bose" AND whose model doesn't contain "soundtouch" are
rejected. Closes the loop on NorbertBauer's diagnostic bundle that
showed a Dreambox dm920 and Onkyo HT-R695 living under the default
account because they answered our generic MediaRenderer:1 probe.
2. New health check: default-account-contains-non-Bose-devices (#269).
Walks devices keyed under data/accounts/default/devices/, flags any
whose ProductCode/Name doesn't look SoundTouch, and offers an Evict
QuickFix. Bose devices still in default (legitimate pre-pair) are
intentionally ignored — that's the consistency check's domain.
3. Clipboard fallback for Copy buttons (#355). The two health-tab Copy
buttons used navigator.clipboard.writeText, which requires a secure
context. Over plain HTTP at a LAN IP the browser blocks it silently
and the button shows "Copy failed". New copyTextToClipboard helper
tries the modern API first, falls back to document.execCommand("copy")
via an off-screen textarea.
4. Web UI static-asset cache-busting (#345). dekiesel needed Ctrl+F5 to
see the v0.89 Download button after upgrade. The root HTML now
carries a ?v=<hash> query string on /web/js/script.js and
/web/css/style.css references. Hash is sha256 over the embedded asset
bodies, truncated to 12 hex chars — stable per binary, changes when
the assets change.
