Services no longer receive the concrete account store. on_command now takes
&mut dyn Store + &dyn NetView (both defined in fedserv-api); the engine's Db
and Network implement them. Reads hand back plain views (AccountView,
ChannelView, ...) carrying only non-secret fields, so the event log, gossip,
and credential material (password hash, SCRAM verifiers) are unreachable from
a module. All command modules ported; behaviour unchanged.
When email is configured and a REGISTER includes an address, the account
starts unverified and a confirmation code is emailed. CONFIRM <code>
verifies it (a federated AccountVerified event); INFO shows an unconfirmed
email until then. Emailed codes now carry a purpose (reset vs confirm).
Adds a config-driven mailer: a SendEmail action the link layer pipes to
a configured command (sendmail -t, msmtp, ...) off-thread. NickServ
RESETPASS <account> emails a short-lived code to the address on file;
RESETPASS <account> <code> <newpassword> completes the reset. Codes are
node-local; the password change itself federates.
A nick can be grouped to an account and then identifies to it; the store
resolves an alias to its account everywhere it authenticates. GHOST (and
RECOVER) rename off a session using a nick you own. Grouped nicks
federate and are dropped with their account.
SET PASSWORD changes your password (derived off-thread like register) and
SET EMAIL sets an address. DROP deletes your account, releases and drops
the channels you founded, and logs you out. A dropped account federates,
and each node logs out any local session that was relying on it.
INFO shows an account's registration date and (to its owner) email; ALIST
lists the channels an account founds or has access on. The UTC time
formatter moves to the db module so both services share it.
Mirrors the chanserv layout: nickserv.rs keeps the service and dispatch,
each command (register, identify, logout, cert) lives in its own file
with its subcommands and parameters. Behaviour is unchanged.
When a peer's registration wins a name a local session was logged into,
that session authenticated against a credential that no longer exists.
The node now clears its accountname (the ircd emits RPL_LOGGEDOUT) and
tells the user why. A new outbound channel lets the engine push these
services-initiated actions to the uplink from the gossip path, drained
by the link loop alongside incoming traffic.
IDENTIFY now takes an optional leading account name, so logging into an
account whose name differs from your current nick works. Without it, the
account still defaults to the current nick as before.
Adds channel moderation commands sourced from the ChanServ pseudoclient.
Tracks connected users' nicks and hosts so targets can be resolved by
nick and banned by *!*@host. All commands require operator access.
