fix: merge dotted+hyphenated FTS5 quoting into single pass

The original PR applied dotted and hyphenated regex quoting in two
sequential steps.  For terms with both dots and hyphens (e.g.
my-app.config.ts), step 2 would re-match inside already-quoted output,
producing malformed double-quoted FTS5 syntax.

Merged into a single regex pass: \w+(?:[.-]\w+)+ — handles dots,
hyphens, and mixed terms in one shot.  Added test coverage for the
mixed case.
