Group the module crates under modules/

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.

+//! HelpServ is a help desk. A user opens a ticket with REQUEST (or HELPME); it
+//! joins a queue that — being event-sourced and surfaced by the engine's audit
+//! feed — is announced to staff and shows up in OperServ LOGSEARCH, the same
+//! trail as reports. Operators work the queue: LIST, VIEW, TAKE (claim), NEXT
+//! (claim the oldest), and CLOSE. A user can CANCEL their own open ticket.
