What: Updated history search interface text for better clarity.
Changes:
- Changed "bck-i-search:" to "search prompts:"
- Changed "failing bck-i-search:" to "no matching prompt:"
- Added visible cursor in search field (previously hidden)
- Evidence: Modified in function at line 425036 in v1.0.127 (was at line 429928 in v1.0.126)
Why it matters: The new prompts use plain language instead of technical terminal jargon, making the feature more discoverable and user-friendly.
