### Selectable percentile and degradation filter on Performance History

Performance history on service overview now supports a selectable percentile — p50, p95, p99, or MAX — in the response-time column header, instead of being fixed to p95. A new degradation filter (All / Degraded \<50% / Degraded ≥50%) lets you focus on operations where the tail is actually regressing against the baseline, with cell coloring reflecting the same severity tiers.

### Improvements

- **AI Assistant**
  - Did-you-mean suggestions on MCP tool calls — when a service or endpoint name doesn't exactly match, the hosted MCP server suggests close matches instead of returning an empty result
- **Discover**
  - ECS view now shows killed and stopped tasks alongside running ones, so you can see failures without losing historical context
- **Control Plane**
  - Rehydration GET API returns `created_by`, so the "Created By" column no longer shows a dash for rehydration rules

### Fixes

- **Control Plane**
  - Drop rules could be overwritten and deleted by stale UI state when multiple edits happened in sequence
  - Rehydration was incorrectly blocked for editors with "Unauthorized user for this action" — now allowed for both editors and admins
- **General**
  - Raw `</details>` tags appeared in the MCP docs section instead of rendering as collapsible content
