feat(auth): automatic logoff after user inactivity (UI API 1.12.0)

Every request of a signed-in session states the age of the operator's last
touch, key or scan in X-QQQ-User-Activity-Age, so the session heartbeat alone
no longer keeps a session alive on a server with a user inactivity timeout.
When the server publishes userInactivityTimeoutSeconds the scanner warns a
minute before and signs out when it runs out; the server ends the session at
the next request regardless. Servers without the value are unaffected.

 # Changelog
 
+## 1.0.4 (versionCode 6)
+
+- Loading the server's metadata no longer fails with "Error loading QInstance: timeout" on a handheld. The metadata response is about 1.7 MB and takes the server 4 to 8 seconds to build, and the default 10 second read timeout expired. That one call now allows 60 seconds; every other call keeps its short timeout. A timeout now reads "Timed out after 60.0s loading the server's metadata from <server>/qqq/v1/metaData".
+- Sign-out now also ends the identity-provider session in the browser when the server supports it (the same flow as "Sign out of company", now behind the single **Sign out** action), and every browser sign-in sends `max_age=0` next to `prompt=login`. Before, ordinary Sign out cleared only the QQQ session, so the provider session left in the browser silently signed the same person straight back in on the next sign-in. Servers without provider logout still get local plus QQQ sign-out. Stored-session restore after sign-out was checked and is not a cause (test added).
+- Includes 1.0.3 (versionCode 5): string widget icons and summary-only help content from current QQQ core are accepted. (PR 24)
+
 ## 1.0.2 (versionCode 4), candidate
 
 Not yet built, signed, tagged or published (prepared 2026-11-06). Supersedes the unpublished signed 1.0.1 (versionCode 3) candidate and updates it in place with the same permanent signer.

 ## Optional company sign-out (implementation awaiting qualification)
 
-Ordinary **Sign out** continues to end only the QQQ session. The scanner also exposes a separate **Sign out of company** action in Account when the server advertises API1.10 or later within major1, feature `nativeSessionLogout`, and OAuth2 metadata `nativeSessionLogout` with flow `OIDC_RP_INITIATED_LOGOUT` and `postLogoutRedirectUris`. Other library hosts opt into that separate action with `LocalCompanySignOutEnabled`; it is disabled by default. No automatic provider-logout policy is selected. The confirmation explains that company sign-out may affect other applications in the browser.
+Since 1.0.4, **Sign out** in Account ends the QQQ session and, when the server advertises API1.10 or later within major1, feature `nativeSessionLogout`, and OAuth2 metadata `nativeSessionLogout` with flow `OIDC_RP_INITIATED_LOGOUT` and `postLogoutRedirectUris`, also ends the provider session in the browser (formerly the separate **Sign out of company** action; without that support Sign out stays QQQ-only). Other library hosts opt into provider sign-out with `LocalCompanySignOutEnabled`; it is disabled by default. No automatic provider-logout policy is selected. The confirmation explains that company sign-out may affect other applications in the browser.
 
 Register the installed package's exact callback separately as a provider **post-logout** redirect, even when it matches the existing login callback. The client sends `{"nativeLogout":{"postLogoutRedirectUri":"<registered callback>"}}` to the existing `POST /qqq/v1/logout`. Its optional `nativeLogoutData` contains `issuer`, `endSessionEndpoint`, `postLogoutRedirectUri` and sensitive `idTokenHint`. Old sessions or unsupported servers may legitimately omit this data. The ordinary logout request remains unchanged.
