The web process built its own PluginManager and loaded plugins into itself:
store installs and updates loaded or reloaded a web-side copy, and config
saves and enable/disable called on_config_change, on_enable and on_disable
on it. None of that reached the panel, and /plugins/installed reported
runtime state from those copies.
- Add PluginCatalog (src/plugin_system/plugin_catalog.py): manifests,
directories, display modes, installed version, schema and config reads,
with no way to run a plugin. app.py and both blueprints use it; the
plugin_manager blueprint attribute is gone.
- Remove every lifecycle call from the web routes. Config changes already
reach the display through ConfigService (on_config_change) and the
enabled-set reconcile.
- Health and metrics readers move to api_v3.health_tracker /
resource_monitor. /plugins/installed reports loaded/state/error_info as
null (the display does not publish them) and enabled by the display's
rule.
- Store install, update and uninstall answer restart_required when the
running display will not pick the change up by itself
(display_restart_required). The restart banner follows the flag via
window.noteRestartRequired instead of the /config/main URL heuristic;
/config/main now sends restart_required: true.
- The one remaining in-process import of plugin code (Starlark helper
modules, oauth_flow action scripts) goes through
_import_plugin_code_in_web_process() until a web-entry contract.
- /plugins/installed reports vegas_participation (from #682) from the
user's setting or the manifest, with vegas_participation_source; when
only the plugin's code decides it, null with source 'runtime', since the
web process no longer has plugin instances to ask.
- Check & Update All keeps its restart flags when the final list refresh
fails, and asks for a restart when an enabled plugin's first request got
no answer and the re-sent one found it up to date.

A plugin takes part in Vegas mode in one declared way: 'scroll', 'pause'
or 'exclude', resolved from the user's vegas_participation setting, the
manifest field, then the legacy hooks, so no plugin changes behaviour.
The stream manager decides inclusion and pauses through it; the installed
plugins API and the Vegas plugin-order list report it. Deprecates
get_supported_vegas_modes, get_vegas_segment_width and vegas_panel_count
for removal in 3.9.0, and regenerates docs/DEPRECATIONS_3.8.md to include
them.
