Teknium d7a2e3ddae fix: handle hyphenated FTS5 queries and preserve quoted literals (#1776) ...

_sanitize_fts5_query() was stripping ALL double quotes (including
properly paired ones), breaking user-provided quoted phrases like
"exact phrase".  Hyphenated terms like chat-send also silently
expanded to chat AND send, returning unexpected or zero results.

Fix:
1. Extract balanced quoted phrases into placeholders before
   stripping FTS5-special characters, then restore them.
2. Wrap unquoted hyphenated terms (word-word) in double quotes so
   FTS5 matches them as exact phrases instead of splitting on
   the hyphen.
3. Unmatched quotes are still stripped as before.

Based on issue report by @bailob (#1770) and PR #1773 by @Jah-yee
(whose branch contained unrelated changes and couldn't be merged
directly).

Closes #1770
Closes #1773
