The service pseudo-clients and the ircd protocol link sat flat at the
repo root, mixed in with the daemon core and the SDK. Move them all
under modules/ so the tree separates concerns cleanly: the daemon in
src/, the SDK every module links against in api/, and the loadable
modules — the pseudo-clients plus the protocol link — in modules/.
Workspace members, the daemon's per-crate dependency paths, and each
module's api path are updated to match; the docs follow. No code change.
Force a user's nick change or channel join, reusing the ForceNick and
ForceJoin actions the daemon already relies on (guest renames, auto-join)
so the ircd support is proven. SVSNICK validates the new nick; SVSJOIN
takes an optional key. Both admin-gated and resolve the target via
NetView.
