/**
|
|
* Fleets - first-party, in-process plugin.
|
|
*
|
|
* This plugin runs on the main thread rather than in a worker for the same
|
|
* reason proxmox and ai do (see src/backend/plugins/first-party.ts): its
|
|
* execute/transfer routes resolve and connect to many hosts concurrently over
|
|
* the shared SSH pool via resolveHostById and withConnection, read/write
|
|
* files over SFTP, and stream a zip archive back for pull requests. None of
|
|
* that fits the worker ctx -- ctx.hosts is a 13-field read-only view with no
|
|
* fleets surface at all, and ctx.http.route replies with a single postMessage
|
|
* value rather than a stream.
|
|
*
|
|
* Like proxmox, this plugin does not own a live transport (no WebSocket
|
|
* server, no dedicated port), so it registers its Express router with the
|
|
* always-mounted /fleets dispatcher in
|
|
* src/backend/database/routes/fleet-dispatch.ts instead of getting its own
|
|
* port.
|
|
*
|
|
* routes.ts is what used to be src/backend/database/routes/fleet-routes.ts,
|
|
* moved here and rewritten from `export default router` into
|
|
* startFleetsService()/stopFleetsService(), called from
|
|
* activate()/deactivate() below. The fleets/fleetMembers/fleetInventory
|
|
* tables and their repositories stay in core (src/backend/database/db/schema.ts,
|
|
* src/backend/database/repositories/fleet-repository.ts,
|
|
* fleet-inventory-repository.ts) -- this plugin system has no owned-table
|
|
* migration mechanism of its own, and these tables carry FKs into core's
|
|
* hosts/users tables.

|
|
* The plugin ships beside dist/backend, so in a built server the compiled

|
* .js for routes.js sits right next to this .mjs, and core modules resolve
|
|
* via ../../../backend/backend/... from there (dist/plugins/fleets/backend
