Release: multi-state trigger profiles with analog wheel, NixOS notify-only updates

[LordVicky]

What's new

Everything since v1.8.0. #23 and #24 reached main earlier (via the #24 dev→main merge); this PR delivers #25 and #26 — listed together here as the full release changelog.

Game Profile tab: per-game hub (#23)

• New default landing page: Nvidia-App-style cover grid where every tile is a trigger profile; "Now Playing" hero with live status chips; Add Game tile with running-process detection; art-less tiles get a deterministic gradient + monogram.
• Per-game hub with a Game Settings / Global Settings scope toggle — the existing full tabs (Audio, Haptics, Trigger Lab, Lighting, Remapping) edit the game's own snapshot, with a scope banner while the hub is open.
• GameSettingsCoordinator auto-switches settings with game detection (single watcher), persists a crash-safe restore point, and restores global selections on exit.
• SteamGridDB cover art with the user's own API key, cached per profile; HTTPS-only, size-capped.

Trigger modifiers, installer, and kernel coverage (#24)

• Hold escalation (hardware-verified): multiple trigger-held-over modifiers on one trigger now escalate — each runs its own timer and the longest satisfied hold wins; non-hold conditions keep first-match priority.
• Installer applies BlueZ disable-input (vds needs raw HID ownership); NixOS gets services.opends5.disableBluetoothInputPlugin.
• Kernel-variant headers resolved per distro: CachyOS variants, XanMod, Liquorix, Nobara fsync, openSUSE flavors; dead LLVM=1 path removed.
• Game Path editor on game profiles for manual process-name matches; About shows the app version.

NixOS notification-only updates (#25)

• The updater notifies on NixOS but never self-replaces the AppImage or rebuilds drivers; declarative flake update workflow documented.
• Nix CI evaluates and builds vds, vds-module, opends5; optional Cachix publishing; opt-in local release endpoint for updater UI testing.

Multi-state trigger profiles (#26)

• States: a game profile holds up to 12 named per-weapon/per-vehicle trigger feels; switching is inferred from controller input, with a menu guard and manual re-anchors.
• Analog wheel: mirrors stick-driven weapon wheels — hold the wheel button, point the left stick, release to commit. Radial configurator with live stick preview, threshold dead zone, rotation offset, and per-slot widths for unequal wheels.
• Sentence switch rules: "When I press [CR + →] → switch to Micer", bound by pressing the real controller button (hold a second button for a chord).
• State position ≡ wheel sector: one number, two synced views; clicking a wheel slice focuses that state in the editor. Live state chips live in the Now Playing hero.
• Validator stays byte-synced with OpenDS5-Profiles (sync-validator --check in CI); the library already serves multi-state profiles — MOUSE: P.I. For Hire ships as the first verified 12-state wheel profile (OpenDS5-Profiles Make companion window freely resizable with persisted bounds #7/Trigger profiles UI polish + engine startup recognition fixes #8).

Docs

• README in-app screenshots (11 pages), multi-state wiki guide + design specs, Discord link, Prerequisites wiki page.

Testing

682 companion tests green, typecheck clean, AppImage/flake/validator-sync CI passing; hold escalation, wheel, and capture rules hardware-validated on a DualSense.

Version bumped to 1.8.1; tagging v1.8.1 after merge publishes the release.
