feat(plugins): show installed state in marketplace and stream install tasks

- report download progress (bytes, speed) and human-readable install stages
  from the plugin runtime connector via the install task context
- add a marketplace installed-state helper so market cards reflect whether a
  plugin is already installed
- surface install progress / queue state in the plugin install-task UI
- extend BackendClient and API entities with install-task status
- i18n for the new marketplace / install strings

+## Runner usage recommendations
+
+Use `search_plugins` with `runner_usage: "agent"` for Agent, pipeline, and
+setup-wizard recommendations, or `runner_usage: "event"` for event processors.
+The component kind remains `Runner`. Only these two exact values are accepted;
+omit the optional field to preserve unfiltered browsing.
+
+```json

+
+Plugin results include `latest_version` and `runner_usages: string[]`, the
+explicit union of usages in that latest installable version. Only recommend a
+plugin when this array explicitly contains the target usage. Missing, empty,
+malformed, or unknown usages must never mean agent-compatible. Event-only
+plugins must never enter Agent recommendations. Empty filtered results are
+valid while legacy packages await corrected releases; never remove the filter
+to fill a recommendation list.
+
+REST callers use `runner_usage` on both
+`POST /api/v1/marketplace/extensions/search` and the compatibility
+`POST /api/v1/marketplace/plugins/search`; preserve it during fallback. Add
+`"type_filter":"plugin", "component_filter":"Runner"` on the unified endpoint.
+Usage is ANDed with other filters before pagination and `total`; MCP/Skill items
+do not match. Invalid REST values return HTTP 400.

+Open the same filter in the webpage:
