Subject: [PATCH] feat(canvas): add max effort level to ConfigTab dropdown
 (#653)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a fifth option to the effort <select> in the Claude Settings section:

  <option value="max">max — absolute ceiling</option>

The dropdown now offers: low / medium / high / xhigh / max.

effort is typed as string? so no interface update required.
Test updated: source-assertion count "four" → "five", new toYaml
serialization test for effort: max.

641/641 tests pass. Build clean.
