Creating new changes against flash1293/action-ralph. Make file changes locally — a separate publish step handles PR creation.

## Tasks

- [x] Understand the request: Implement a Streams UI easter egg: when the stream search query is "Where is Elky?" (case-insensitive, surrounding whitespace ignored), render an elk emoji banner above the main Streams list table.

Requirements:

1. Implement the behavior in the Streams UI code path used for the main list/table.
2. Add/adjust unit tests to cover:
   - exact phrase match
   - case-insensitive match
   - no banner for other queries
3. Run scoped validations before finishing:
   - at least one relevant Jest test run
   - scoped type check for the touched project
4. In the final spec, include the exact validation commands and whether they passed.

- [x] Plan and expand this into concrete implementation tasks based on what you find. Keep in mind each task runs in a separate agent session with fresh context, so each should be self-contained. Include validation (run tests).
- [ ] Implement the Elky easter egg: Add logic to detect "Where is Elky?" query (case-insensitive, trimmed) in `tree_table.tsx` and render an elk emoji banner above the table when detected. Add unit tests in a new test file `tree_table.test.tsx` to verify: exact match, case-insensitive match, and no banner for other queries. Run Jest tests and scoped lint/type-check for the streams_app project.
- [ ] Final validation: Run full scoped type-check for the touched tsconfig, confirm all tests pass, update spec status to "done".

## Definition of done

All requested changes are implemented, tests pass, and the spec status is set to "done".

## Additional Context

### Code Structure Discovery (Task 1)

**Main Streams List Component:** `/home/runner/work/kibana/kibana/x-pack/platform/plugins/shared/streams_app/public/components/stream_list_view/tree_table.tsx`

- This is the core component that renders the streams table
- Uses `EuiInMemoryTable` with integrated search
- Search query state: `searchQuery` (line 88, type: `Query | undefined`)
- Search handler: `handleQueryChange` (lines 217-219)
- The search query text is accessible via `searchQuery?.text`

**Parent Container:** `/home/runner/work/kibana/kibana/x-pack/platform/plugins/shared/streams_app/public/components/stream_list_view/index.tsx`

- Renders `StreamsTreeTable` component at line 242
- Also renders callouts above the table (lines 234-241): `WelcomeTourCallout` and `LegacyLogsDeprecationCallout`
- Pattern: Callouts are rendered BEFORE the table component

**Search Implementation Details:**

- Search query filtering happens in `tree_table.tsx` lines 177-181
- Free text is extracted from `searchQuery?.text` after removing data quality patterns
- The `searchQuery` object has both `.text` (string) and `.ast` (parsed query structure)

**Test Structure:**

- Existing test file: `utils.test.ts` tests utility functions
- No existing `tree_table.test.tsx` - we'll need to create one
- Test pattern: Jest unit tests using `@testing-library/react` or similar for component testing

**TypeScript Config:**

- Project path: `/home/runner/work/kibana/kibana/x-pack/platform/plugins/shared/streams_app/tsconfig.json`

### Implementation Plan (Task 2)

**Strategy:**

1. In `tree_table.tsx`, add a `useMemo` to detect the easter egg query
2. Render an elk emoji banner (using EUI components) conditionally above the `EuiInMemoryTable`
3. Create `tree_table.test.tsx` with unit tests for:
   - Detection logic (case-insensitive, trimmed)
   - Banner rendering when query matches
   - No banner for other queries
4. Run validation:
   - `yarn test:jest <test-file-path>`
   - `node scripts/eslint.js x-pack/platform/plugins/shared/streams_app/public/components/stream_list_view/tree_table.tsx --fix`
   - `yarn test:type_check --project x-pack/platform/plugins/shared/streams_app/tsconfig.json`

**Easter Egg Detection Logic:**

```typescript
const showElkyBanner = useMemo(() => {
  const query = searchQuery?.text?.trim().toLowerCase() ?? '';
  return query === 'where is elky?';
}, [searchQuery?.text]);
