docs(agents): prefer Observation framework

 - Gateway currently runs only as the menubar app (launchctl shows `application.com.steipete.clawdis.debug.*`), there is no separate LaunchAgent/helper label installed. Restart via the Clawdis Mac app or `scripts/restart-mac.sh`; to verify/kill use `launchctl print gui/$UID | grep clawdis` rather than expecting `com.steipete.clawdis`. **When debugging on macOS, start/stop the gateway via the app, not ad-hoc tmux sessions; kill any temporary tunnels before handoff.**
 - macOS logs: use `./scripts/clawlog.sh` (aka `vtlog`) to query unified logs for subsystem `com.steipete.clawdis`; it supports follow/tail/category filters and expects passwordless sudo for `/usr/bin/log`.
 - Also read the shared guardrails at `~/Projects/oracle/AGENTS.md` and `~/Projects/agent-scripts/AGENTS.MD` before making changes; align with any cross-repo rules noted there.
+- SwiftUI state management (iOS/macOS): prefer the `Observation` framework (`@Observable`, `@Bindable`) over `ObservableObject`/`@StateObject`; don’t introduce new `ObservableObject` unless required for compatibility, and migrate existing usages when touching related code.
 - **Multi-agent safety:** do **not** create/apply/drop `git stash` entries unless Peter explicitly asks. Assume other agents may be working; keep unrelated WIP untouched and avoid cross-cutting state changes.
 - When asked to open a “session” file, open the Pi session logs under `~/.clawdis/sessions/*.jsonl` (newest unless a specific ID is given), not the default `sessions.json`.
 - Menubar dimming + restart flow mirrors Trimmy: use `scripts/restart-mac.sh` (kills all Clawdis variants, runs `swift build`, packages, relaunches). Icon dimming depends on MenuBarExtraAccess wiring in AppMain; keep `appearsDisabled` updates intact when touching the status item.
