feat(h707): Blind search - initial implementation (#708)

# feat: Blind search - initial implementation

## Description

Blind Search Tagbox (h707): hide tagbox choices until the user types
enough characters, then use native SurveyJS filtering, with an **Other**
fallback when there are no matches. Includes code review hardening for
creator multi-instance cleanup, lazy-load callbacks, HMR, and extension
detection.

### Feature

- Added `blind-search-tagbox` feature slice under
`lib/survey-features/blind-search-tagbox/` with Serializer props
`edxHideUntilTyping` and `edxMinSearchLength` (tagbox only)
- Implemented pure logic in `blind-search-state.ts`: threshold
suppression, choice filtering, lazy-load detection, and Other-fallback
rules
- Wired runtime handlers in `survey-bindings.ts` for `onChoicesSearch`,
`onPopupVisibleChanged`, and `onValueChanged` to hide choices on open,
filter at/above threshold, and manage Other state
- **Inline choices:** empty dropdown until threshold; show **Other** in
the list only when search returns no matches
- **Data-list / lazy load:** integrated with shared lazy-load guard to
suppress fetches below threshold; apply Other fallback after fetch
completes via completed-handler hook
- **Other UX:** show Other in dropdown without enabling the comment area
until selected; close popup on Other selection to avoid overlay issues;
restore `showOtherItem` when Other is deselected
- Registered dynamic extension in `core-registry.ts` with `shouldLoad`
via new `hasCustomProperty("edxHideUntilTyping")`
- Added `use-blind-search-tagbox.hook.ts` and
`initBlindSearchTagboxGlobals()` call in form editor for creator support
- Extended data-lists `survey-bindings.ts` to consult lazy-load guards
before fetch and notify completed handlers after `setItems`
- Added shared `choices-lazy-load-guards.ts` registry for cross-feature
lazy-load suppression and post-fetch callbacks

### Initial code review fixes

- Replaced module-level `trackedQuesti... (continued)
