Splits the three grouped router files into eight api_<verb>_<resource>.py modules under decnet/web/router/swarm/ to match the convention used by router/fleet/ and router/config/. Shared request/response models live in _schemas.py. Keeps each endpoint easy to locate and modify without stepping on siblings.

"""POST /swarm/deploy — shard a DecnetConfig across enrolled workers.
|
|
|
|
Per worker we build a filtered copy containing only the deckies assigned
|
|
to that worker (via ``host_uuid``), then POST it to the worker agent.
|
|
The caller is expected to have already set ``host_uuid`` on every decky;
|
|
if any decky arrives without one, we fail fast. Auto-sharding lives in
|
|
the CLI layer, not here.
