feat(agents): set team to software-development on BMM agents

All six BMM agents (analyst, tech-writer, PM, UX designer, architect,
dev) now explicitly declare `team: software-development` in the
module.yaml roster instead of falling back to the module-code default
of `bmm`.

This matches the BMad-wide team convention where agents across modules
that collaborate on software delivery share one named team. Tea's Murat
joins the same team via a parallel PR in bmad-method-test-architecture-
enterprise so party-mode, help catalog, and retrospective skills can
route the full software-delivery roster as a single unit.
