Add query title heading and matched token to output

- buildMarkdownOutput now prepends '# Results for "query"' (H1) with
  optional qualifiers (· including archived · excluding templates).
  In regex mode the query is displayed in backticks.
- Each match line appended with the exact matched token in backticks
  when TextMatchSegment.text is available (e.g. \`: \`useFlag\`\`).
- buildJsonOutput adds matchedText field to each match entry alongside
  the existing line/col fields (omitted when location is unavailable).
- repo-only mode also gets the H1 heading before the repo list.
- New exported buildQueryTitle(query, options) in src/output.ts.
- 78 tests pass (new describe + updated snapshots in output.test.ts).
- README.md and docs updated to reflect new output format.

Closes #126
