N/A

Summary of the issue:

Find Next and Find Previous did not consistently move between individual search matches, especially when multiple results appeared on the same line. When no result existed in the requested direction, the cursor could still move without a clear user-facing message.

Description of how this pull request fixes the issue:

This updates search result navigation so F3 and Shift+F3 move to the next or previous actual search match and select the matched text.

If there is no next or previous result, Bookworm now keeps the cursor and selection unchanged, plays the existing navigation feedback sound, and announces a short localizable message.

The search results dialog also updates the current search result state, so Find Next/Previous continues from the result selected in the dialog.

Testing performed:

Manual testing performed for:

• F3 / Shift+F3 across multiple matches on the same line.
• F3 / Shift+F3 after selecting a result from the search results dialog.
• No next / previous result behavior, including cursor not moving and feedback being announced.
• Regex search results, including zero-width match fallback behavior.

Also ran:

• uv run --no-sync pytest tests\test_search.py -q
• uv run --no-sync pytest -q
