Feat/members messaging (#29)

* fix(deploy): build Go binaries on the runner, ship them, SKIP_BUILD on box

The deploy SSHed into the ~458MB droplet and ran `go build` there. The Go
linker's peak memory OOM-killed the build — and with it the sshd serving the
deploy session — surfacing as "Connection closed by remote host" (exit 255).
It was flaky because it tracked momentary memory pressure from the co-resident
ergo/forgejo/tor/podman/agentbbs processes (run #25 passed, #26 failed on
near-identical code).

Build both binaries on the 16GB GitHub runner instead (pure-Go, modernc
sqlite, so CGO_ENABLED=0 static cross-build), scp them to the droplet, and run
setup.sh with SKIP_BUILD=1 so the box never compiles. Arch is detected from
the droplet so amd64/arm64 both work. setup.sh now also skips the Go toolchain
download when SKIP_BUILD=1.

* feat(members): member directory + store-and-forward messaging

A members-only hub plugin (the BBS "who") plus user-to-user messaging:

- internal/store: messages table + SendMessage/Inbox/UnreadCount/MarkRead, and
  OnlineUsers (open sessions) for presence. MarkRead is recipient-scoped so a
  member can only clear their own mail.
- plugins/members: directory with online dots + last-seen, a finger-style
  profile view, a minimal compose box, and an inbox that marks read on open.
- ssh msg@host <user> [text]: scriptable CLI to leave a note (body from args or
  stdin), mirroring the existing finger route; "msg"/"message" are reserved.
- hub: "N unread" badge on login (hubMOTD). plugin.Context gains Host for member
  homepage URLs.

Extends the existing finger@ behavior (ssh <name>@host) rather than replacing it.
