offscale is a plugin

headscale leaves the platform. 45 files move to plugins/offscale/ and the
platform stops knowing it exists.

  api/router.ts   the thin auth-gated proxy, now at /api/offscale
  sidecar/        18 files, the whole headscale contract and its admin keys
  db/             schema + queries, offscale_servers
  web/            26 files as panels and a layout — no screen, per the rule

removed from the platform: the hono mount, the `headscale` capability, the
App.tsx route pair, the screen and its barrel, the AppRegistry spread, the
officerdev re-exports, the dock tile, the page-title rule, and both database
barrels. tsgo is clean and nothing references it.

the imports tell the story of what the plugin↔host API actually is. the sidecar
takes @@/sidecar/protocol, @@/sidecar/connect, @@/data-path and
@@/officer-url.mjs; the queries take officerdb/db and officerdb/crypto; the
schema takes officerdb/auth/schema for the one reference a plugin may make; the
web half takes useClient, copyToClipboard, WorkspaceView and TerminalView from
the officerdev barrel. all of it resolves because a plugin lives inside the repo
— no publishing, no version negotiation.

AND IT FOUND A REAL BUG IN THE INSTALLER. createSidecarProxy learns its port
from a one-shot `<name>:server` event and subscribes when the plugin's router is
first imported — at mount. install started the sidecar BEFORE mounting, so the
announcement fired into a void: process online, routes mounted, every request
answering `503 sidecar not available` until something forced a reconnect. it
would have hit every plugin with an http sidecar. `example` never caught it
because it has no listener to announce.

install and enable now mount before starting; disable still unmounts before
stopping. neither direction leaves a mounted route in front of a sidecar that
cannot be reached.

verified live: /api/offscale/_officer/servers answers {"servers":[]}, /offscale
and /offscale/nodes serve, the old /api/headscale is 404, the offscale
capability is registered from the manifest, and officer-offscale is online.

757 pass, same 10 pre-existing failures.
