Every TopologyKind now runs, mapped to five execution patterns:
- hierarchical ← hub_spoke, star_moe, market
- pipeline ← ring
- swarm ← flat, holacratic
- mesh (new) ← blackboard (two peer-exchange rounds + aggregate)
- debate (new) (propose → critique → revise → judge)
execute()'s match is now exhaustive (adding a kind upstream forces an executor),
so the Unsupported error is gone. Benchmark spans all five distinct patterns.
14 tests with --features provider; clippy clean. Doc updated.
