Stage 2 of the web plugin catalog, after #688.
- The display publishes a plugin runtime snapshot (plugin_runtime.py) to
the shared cache: per plugin loaded, lifecycle state, a short redacted
error summary, the version it loaded and when, plus published_at /
stale_after / running. Written on change (throttled to 10 s; the
RUNNING/ENABLED flip of an ordinary update is not a change) and once a
minute otherwise; cleanup() publishes running: false.
- The web reads it back and restores loaded / state / error_info in
/api/v3/plugins/installed (plus loaded_version, loaded_at and
data.runtime). Only a live snapshot counts; stale, stopped or missing
answers null and says which.
- data/plugin_state.json is retired: every reader and writer moved to
config + disk (desired) or the snapshot (observed). Nothing in it was
non-derivable, so nothing is migrated and an existing file is left
unread. The web-side PluginStateManager (state_manager.py) is removed;
the display's plugin_state.PluginStateManager is the only state machine.
- StateReconciliation compares config + disk with the snapshot, reporting
enabled-but-not-loaded and older-version-loaded as no_action findings.
- Backups list installed manifests with enabled from config.json.

- load_plugin: an on_enable() that raises unregisters the instance, so the
next load retries instead of returning True "already loaded".
- get_plugin_info: guard plugin.get_info(); one plugin raising no longer
breaks /api/v3/plugins/installed.
- plugin_state.json and the operation history are written with
atomic_write_text under their lock.
- plugin_loader: module-level lock serialises pip installs across the
parallel startup loaders.
- store_manager._install_via_download: extract dir cleanup moved to finally.
- Test doubles: draw_image() warns (DeprecationWarning; the real
DisplayManager has none), MockDisplayManager.draw_text accepts the real
signature's optional params, VisualTestDisplayManager logs draw errors at
WARNING.
- Docs/comments: compatibility.py method name, PluginState.LOADED meaning,
brittle schema count, why _report_skip_once uses setdefault.
- Remove unused PluginOperationQueue.get_active_operations().
