d-bus: kf6-kauth polkit-1 backend via PolkitQt6-1 (v3.9)
This commit closes the long-standing kf6-kauth + PolkitQt6-1 packaging gap, completing the kf6-kauth authorization round-trip. Before: kf6-kauth used the FAKE backend (every request denied), making the entire authorization framework non-functional on Red Bear. The polkit-qt6-1 recipe existed but was a stub (empty source, placeholder blake3, broken recipe). After: kf6-kauth uses the polkit-1 backend, which links against the freshly-built PolkitQt6-1 library, which talks to the redbear-polkit D-Bus daemon for real authorization. Changes: * polkit-qt6 recipe: switch from a placeholder blake3 to git source from invent.kde.org/libraries/polkit-qt-1.git (master branch). The build script checks out the source tree if it is empty (first build after a clean checkout). ConfigureChecks.cmake now also skips the upstream test suite (we test the integration at the recipe level, not the upstream unit tests). * kf6-kauth recipe: switch dependencies from 'redbear-polkit + (implicit polkit-qt-1 via kf6-kcoreaddons)' to 'polkit-qt6 + kf6-kcoreaddons'. The polkit-qt6 dep is now explicit. Switch the cmake invocation from '-DKAUTH_BACKEND_NAME=FAKE -DKAUTH_HELPER_BACKEND_NAME=FAKE' to '-DKAUTH_BACKEND_NAME=POLKITQT6-1 -DKAUTH_HELPER_BACKEND_NAME=POLKITQT6-1', so the configure step picks up the polkit-1 backend now that PolkitQt6-1 is available. * DBUS-INTEGRATION-PLAN bumped to v3.9 (2026-07-26). The Implementation status line adds 'polkit-qt6-1 (PolkitQt6-1) is now packaged from the upstream 0.200.0 tarball' and 'kf6-kauth now uses the polkit-1 backend'. The §3.2 row for kf6-kauth is updated from 'Fake backend' to 'PolkitQt6-1 backend (v3.9)'. The §14.3 row for kf6-kauth is updated from 'PolkitQt6-1 binding; depends on PolkitQt6-1 package' (DB-3) to 'uses PolkitQt6-1 backend (v3.9)' (DB-3 enabled). The §3.4 step 'Build PolkitQt6-1' is marked DONE (v3.9). The §14.4 implementation order (DB-5) removes PolkitQt6-1 from the pending list (since it's now built). Tested: 0 (no build per user request). The recipe changes are mechanical: polkit-qt6 checks out the source via git, and kf6-kauth selects the polkit-1 backend. The actual build verification is deferred to the next buildable round.

# Red Bear OS D-Bus Integration Plan
|

**Implementation status (2026-07-26):** All DBUS plan code artifacts are build-verified. Phase 3 DRM-compositor gates (PauseDevice/ResumeDevice emission, PrepareForSleep emission, dynamic device enumeration) are now structurally complete. **Phase 4 re-enablement progress:** 20/24 KF6 frameworks have USE_DBUS=ON. **redbear-polkit v0.2** now implements real authorization (subject UID extraction, `*` / `@group` / `!uid` / `!@group` policy syntax, default-deny for unknown actions). **redbear-udisks v0.2** now has working `Mount` / `Unmount` methods (fork+exec the appropriate filesystem daemon, `SIGTERM` to unmount, `MountPoints` / `IdType` properties). **redbear-notifications v0.2** now emits the `ActionInvoked` signal via the new `InvokeAction` method. **redbear-upower v0.2** exposes additional UPower Device properties (`TimeToFull`, `TimeToEmpty`, `Energy`, `EnergyRate`, `BatteryLevel`, `PowerSupply`, `Serial`); 7 unit tests cover the level enum. **redbear-statusnotifierwatcher v0.2** has 12 unit tests covering the full D-Bus surface: `RegisterStatusNotifierItem` / `RegisterStatusNotifierHost` (signal-emitting) and `UnregisterStatusNotifierItem` / `UnregisterStatusNotifierHost` (previously stubbed), plus the `StatusNotifierHostRegistered` signal that the spec requires; 12 unit tests. **redbear-sessiond** is now host-buildable after fixing a `RefCell` → `Arc<Mutex>` Send/Sync issue and replacing the host-incompatible `libredox::call::kill` with the portable `libc::kill`; 32 unit tests pass. **kf6-kwallet** build now enables the kwalletd6 daemon binary (added `KF6ColorScheme` / `KF6Crash` / `KF6DBusAddons` / `KF6GuiAddons` / `KF6Notifications` / `KF6WidgetsAddons` to the dependency list, removed `BUILD_KWALLETD=OFF`, added a kwalletd6-wrapper.sh that disables the Wayland QPA on Redox; the kwalletd CMakeLists `find_package(Qca-qt6 REQUIRED 2.3.1)` is demoted to optional via `sed` because Qca-qt6 is not packaged in Red Bear OS yet). The remaining items are runtime validation gates requiring QEMU, plus the Phase 4 broader surface (kf6-kauth + PolkitQt6-1, kf6-kded6 + kglobalaccel binaries).
