## What changed
Add `active_plugin_ids_at_turn_start` to turn analytics, combining active host plugins with selected plugin packages. Prefer remote plugin IDs when present and otherwise use validated package IDs. Sort and deduplicate the inventory.
Report `null` for unknown inventories, invalid IDs, IDs longer than 128 bytes, or inventories exceeding 512 distinct IDs; preserve `[]` for an observed empty inventory. Keep the first received inventory even when later resolved configuration updates arrive.
## Testing
Add coverage for ID selection and validation, deduplication, size limits, serialization, and preservation of the first inventory. Extend app-server tests to check inventories after plugin reconciliation and with selected plugins, including turns without explicit plugin mentions.

## What changed
- Add the `plugin/reconcile` JSON-RPC method to synchronize installed remote plugin bundles and wait for required hook updates.
- Return affected plugin IDs with MCP, Apps, hooks, and skills refresh hints, plus remote update and materialization failures.
- Refresh loaded hook runtimes after relevant updates and return an empty result when plugins or backend authentication are unavailable.
## Testing
- Cover workspace and global bundle installs, unchanged passes, enablement changes, updates, removals, materialization failures, hook refreshes, and disabled plugins.
