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.
JUPE <server.name> [reason] introduces a fake server holding the name so
the real one can't link; JUPE DEL <name> squits it; JUPE LIST shows them.
Node-local (the introducing node owns the jupe, so it isn't federated —
that would collide SIDs across nodes) and re-asserted at burst. A fake
server id is allocated per jupe. New JupeServer/Squit actions serialise to
the mid-link SERVER introduction and SQUIT. Admin-only.
