docs(AGENTS): refresh to match current codebase

- remove hardcoded ADB serial (differs per developer/machine)
- add second pre-commit hook (check_version_sync) to hard rules
- document tests/, scripts/, backdrops/, CI-SETUP.md in layout
- note committed tests/test_android.py copy + test_android_http.py

 ## Hard rules
 
 - `hermes-agent/` is a **read-only research reference** (git-ignored). Never commit, push, or modify it — a pre-commit hook (`scripts/guard_hermes_agent.sh --staged`) fails any commit that stages it. Never modify hermes core; we only install our plugin into the live hermes home.
+- A second pre-commit hook (`scripts/check_version_sync.sh`) fails any commit where the `gateway-plugin/plugin.yaml` version ≠ the repo-root `VERSION` file — keep them in sync.
 - **Commit/push scope:** when asked to "commit and push all changes," that means **all** changes in the working tree — it does NOT matter whether a change was made this session or earlier. Stage everything (`git add .`) and commit; do not cherry-pick or second-guess which files are "yours." The only exception is `hermes-agent/` (git-ignored, never staged).
 - The plugin is installed by symlink: `~/.hermes/plugins/iris` → `<repo>/gateway-plugin` (already set up on this machine).

 - `gateway-plugin/` — Python hermes platform plugin (`android`). No build step, zero new deps (stdlib + hermes-provided `websockets`/`httpx`). `protocol.py` is the frame source of truth, mirrored in `app/shared/.../protocol/Protocol.kt` and `docs/protocol/frames.schema.json`.
 - `app/` — one Compose Multiplatform Gradle project: `:shared` (KMP, most of the code; `jvmMain` is shared by the android and desktop targets since both are JVM-based), `:androidApp` (thin shell, package `dev.iris.app`), `:desktopApp` (thin shell).
 - `docs/` — numbered reference library; read `docs/00-overview.md` first. Locked decisions: `docs/16-open-questions.md`.
+- `tests/` — committed Python test suite: `test_android.py` (plugin tests; a copy of the hermes-agent mirror described below), `test_android_http.py` (HTTP fallback transport, see `docs/19-http-fallback-transport.md`), `ws_probe.py`, `e2e.py`, `README.md`.
+- `scripts/` — pre-commit guards (`guard_hermes_agent.sh`, `check_version_sync.sh`) and `make_release_keystore.sh`.
+- `backdrops/` — backdrop/wallpaper images (Pexels) used by the app theme.
+- `CI-SETUP.md` — Gitea CI/release setup reference.
 
 ## Commands
 
 - `hermes` is **not on PATH**: use `hermes-agent/.venv/bin/hermes` (venv from `cd hermes-agent && uv sync`).
 - Gateway: `hermes gateway setup` (one-time; generates `IRIS_TOKEN` in `~/.hermes/.env`, prints the token only once) → `hermes gateway` (run) → `hermes gateway status`.
-- Android: check the device is connected first (`adb devices` → `a5ca2a4b` listed as `device`); then `cd app && ./gradlew :androidApp:installDebug` to install on the phone and live-verify changes (launch/screenshot: see ADB below).
+- Android: check the device is connected first (`adb devices` → your device's serial listed as `device`; the serial differs per developer/machine); then `cd app && ./gradlew :androidApp:installDebug` to install on the phone and live-verify changes (launch/screenshot: see ADB below).
 - Desktop: `cd app && ./gradlew :desktopApp:run`; packaging: `:desktopApp:jpackage` (app-image; `-PjpackageType=deb` for a .deb).
 - Python tests — **never bare `pytest`**: `cd hermes-agent && scripts/run_tests.sh tests/gateway/test_android.py` (no args = full suite).
 - Kotlin tests: `cd app && ./gradlew :shared:testAndroidHostTest` / `:shared:desktopTest` (host-side; `jvmTest` is the shared source set).

 ## Testing quirks
 
-- `hermes-agent/tests/gateway/test_android.py` is a thin mirror that imports the **live `gateway-plugin/` package from this repo** (override with `IRIS_PLUGIN_DIR`); HERMES_HOME is sandboxed per-test by the conftest. Tests must never touch the real `~/.hermes`.
+- `hermes-agent/tests/gateway/test_android.py` is a thin mirror that imports the **live `gateway-plugin/` package from this repo** (override with `IRIS_PLUGIN_DIR`); the committed `tests/test_android.py` is a copy of it, and `tests/test_android_http.py` covers the HTTP fallback transport. HERMES_HOME is sandboxed per-test by the conftest. Tests must never touch the real `~/.hermes`.
 - e2e scenarios 3 (reasoning) and 5 (commentary) are model-dependent → SKIP; 11 (push) and 12 (reconnect) are PARTIAL by design.
 - ADB: launch `adb shell am start -n dev.iris.app/.MainActivity`; reset pairing state `adb shell pm clear dev.iris.app`; screenshot `adb exec-out screencap -p > /tmp/shot.png`.
 - ADB UI taps: **never guess tap coordinates from a screenshot** — dump the hierarchy and tap the element's real bounds: `adb shell uiautomator dump` → `adb pull /sdcard/window_dump.xml` → find the node by `text` / `content-desc` / `resource-id` → `adb shell input tap` at the center of its `bounds="[x1,y1][x2,y2]"`. Re-dump after every navigation; if a tap misses, the dump is stale — re-dump, don't nudge coordinates.
