b0d7e8aae2 feat(spotify): wire preset storage end-to-end via server-centric priming (#302)
storePreset on the speaker was failing with "AddPreset - failed due to
invalid SourceID" because the watchdog priming path only pushed ZeroConf
credentials and never registered a SPOTIFY ConfiguredSource in marge.

PrimeDeviceWithSpotify now:
- resolves the device's paired account via live :8090/info
(margeAccountUUID), falling back to ServiceDeviceInfo.AccountID — same
order as setup.populateDeviceInfo;
- writes a SPOTIFY ConfiguredSource under that account (providerID=15,
BoseSecret as credential), mirroring bridgeSpotifyToMarge;
- POSTs `<updates><sourcesUpdated/></updates>` so the speaker re-fetches
its on-device Sources.xml from marge.

Also introduce zeroconf.ErrAddUserNoOp for the narrow firmware quirk
(404 + empty body on ?action=addUser when activeUser already matches).
Recognised only on that exact pattern; real 4xx/5xx still surface loudly
with full response details. Same treatment applied to Amazon priming.

Docs:
- new docs/concepts/spotify-overview.md anchors the topic (mental model,
streamingoauth.bose.com DNS gotcha, token lifecycle, clientId notes,
troubleshooting table);
- spotify-oauth.md drops the removed install-primer endpoint and the
on-device boot-primer install sections, adds /mgmt/spotify/prime;
- spotify-priming-strategy.md and MUSIC-SERVICES.md link to the
overview.

Tobias GesellchenandClaude Opus 4.7 dc1f811a81 docs(zeroconf): clearer literal-IP error and a Security Considerations note
Building on the strict literal-IP validator from the previous commit,
make the runtime error self-explanatory so anyone tripping on a
hostname URL can fix it in one shot:

* Errors now lead with the offending zeroconf URL and the rejected
  host, so wrapping by GetInfo / PushCredentials / pushSimplifiedToken
  doesn't bury the actual bad value.
* The "host must be a literal IP" error suggests two concrete one-liner
  resolutions (`getent hosts <name>` and `dig +short <name>`) so the
  user has a copy-paste fix.
* The "host is not on a local network" error names the accepted ranges
  (loopback / RFC1918 private / link-local v4+v6) so the user knows
  what they're allowed to pass.

docs/guides/SOUNDTOUCH-SERVICE.md gains a bullet under Security
Considerations explaining the constraint and the rationale (LAN-resident
SSRF surface), so the strict behaviour is documented rather than a
surprise.

The 17 TestValidateZcBaseURL cases still pass — only the message bodies
changed.

Tobias GesellchenandClaude Opus 4.7 fbde4e136f fix(security): tighten zeroconf URL validation to literal local IPs
CodeQL re-fired three new go/request-forgery alerts (#134/135/136) on
the lines my previous validateZcBaseURL refactor introduced. The
previous validator accepted hostname-style hosts unchanged, so even
though the IP-class check ran when applicable, u.String() at the call
sites still emitted the original tainted host into the request URL —
which is exactly what CodeQL traces.

Tighten validateZcBaseURL to:

* require the host to parse as a literal IP — DNS / mDNS hostnames
  are rejected (with a clear error explaining the caller should
  resolve to a private IP first); doing the lookup inside the
  validator would re-introduce the SSRF surface CodeQL is flagging,
  because malicious DNS could point a *.local name at a public host
  between the lookup and the request.
* require that IP to be loopback / RFC1918 private / IPv4-or-IPv6
  link-local. Anything else (global IPs in either family) is refused.
* rebuild the returned *url.URL from validated components — scheme
  (already checked), the validated IP literal joined with the
  original port, and the original path. Pre-existing query/fragment
  are stripped so callers attach their own ?action= cleanly. CodeQL
  recognises this fresh-construction pattern as taint sanitisation.

In practice this matches what SoundTouch speakers actually announce:
IP-based zeroconf URLs at port 8200 against an LAN address. The
existing PushCredentials_FullRoundTrip and FallbackOnGetInfoFailure
tests already exercise the loopback path through httptest.NewServer
and pass unchanged.

Adds TestValidateZcBaseURL covering 17 inputs — 9 accept (loopback,
private 10/172/192, link-local v4, IPv6 loopback, IPv6 link-local,
strips query) and 8 reject (public IPv4, public IPv6, hostname,
plain hostname, ftp/file schemes, empty host, unparseable) — to lock
the new contract in.

Tobias GesellchenandClaude Opus 4.7 fb75c8b1f3 fix(security): validate zeroconf URLs against local-network allowlist
CodeQL alerts #121, #122, #123 (go/request-forgery) flagged the three
client.Get / client.PostForm sites in pkg/service/zeroconf/zeroconf.go
that build their request URL by string-concatenating the caller-supplied
zcBaseURL with "?action=…". The base URL ultimately originates from a
device-pairing payload that the speaker pushes to us, so unvalidated
input could redirect outbound HTTP requests to arbitrary hosts (server-
side request forgery).

Add validateZcBaseURL which:

* parses zcBaseURL via net/url so the scheme and host are first-class
  values rather than substrings,
* requires the scheme to be http or https,
* rejects literal IP hosts that aren't loopback / RFC1918 private /
  link-local — those are the only places a real SoundTouch speaker
  can live on a local network, and a global IP would be an obvious
  exfiltration target,
* leaves hostname-style hosts (e.g. mDNS *.local) accepted: name
  resolution itself is a separate trust boundary on the local segment.

A small withAction helper builds the per-call URL from the validated
base URL via url.Values rather than string concatenation, which CodeQL
recognises as a non-tainted construction.

GetInfo, PushCredentials and pushSimplifiedToken each call
validateZcBaseURL up-front so all three CodeQL alerts close in a
single pass. PushCredentials also re-validates even though it then
calls GetInfo (which validates again) so the fallback to
pushSimplifiedToken on getInfo failure is also gated.

Tobias GesellchenandClaude Sonnet 4.6 f1c2b7a53f feat: implement HandleBoseAmazonToken and wire amazonService into Server
- Add GetAccountByRefreshToken to amazon.Service — the speaker sends
  the bare Atzr| refresh token (extracted from AmazonSecret JSON), not
  a surrogate, so lookup must match against Account.RefreshToken
- Add amazonService field, SetAmazonService and IsAmazonConfigured to
  Server (step 5 essentials required by the handler)
- Replace HandleBoseAmazonToken 501 stub with full implementation:
  lookup by refresh token → RefreshAccessToken; fallback to
  GetFreshToken; fallback to HandleBoseProxy if no service configured;
  scope intentionally omitted from response
- Add handler tests covering the by-refresh-token path (mock LWA
  server), the default-account path, and the no-service fallback
- Unlock assertions in post_oauth_token_amazon.http integration test

Tobias GesellchenandClaude Sonnet 4.6 466e9eca97 feat: extract shared ZeroConf package and add Amazon Music OAuth service
- Extract DH key exchange crypto from pkg/service/spotify into new
  pkg/service/zeroconf package with exported functions and
  AuthTypeOAuthToken constant (both Spotify and Amazon use auth type 4)
- Reduce pkg/service/spotify/zeroconf.go to thin wrappers around the
  shared package; public API (PushSpotifyCredentials, ZeroConfGetInfo)
  is preserved
- Add pkg/service/amazon package mirroring the Spotify service with
  Amazon-specific differences: LWA endpoints, POST body credentials
  (not Basic Auth), user_id/name profile fields, amazon/accounts.json
- Add PushAmazonCredentials delegating to shared zeroconf.PushCredentials
