refactor(cli): class-level disabled_toolsets default instead of per-site getattr

Inspection surfaces run on partially built HermesCLI instances (tests use
HermesCLI.__new__), so the attribute needs a default; declare it once on
the class next to _seeded_first_message rather than getattr at five sites.
