one boot path for the workers and the API (V-639)

run() wired the daemon twice and the lists drifted: seven workers started
untracked on the unlock path, a shadowed WaitGroup hid the voice server, and
nexus and getMCPServers were never set after a passkey unlock.

newDaemonAPI and startBackground in cmd/mavend/boot.go are the one place both
paths go through now. backgroundWorkers is the pure list behind the second, so
the set is assertable without a running daemon.

 V-639. Reads with `docs/operations.md`.
 
+## What landed
+
+`cmd/mavend/boot.go`. `newDaemonAPI(deps)` builds the CoreAPI with every field
+set, and `startBackground(ctx, &wg, deps)` starts the voice server and every
+worker through `goWorker`. `backgroundWorkers(deps)` is the pure list behind it,
+so a test can compare the set without standing a daemon up. Both paths in
+`run()` now read `coreAPI = newDaemonAPI(depsNow())` and one
+`startBackground(...)`, where `depsNow` reads whatever the current path wired.
+
+The shadowed `wg` is gone. Four tests in `cmd/mavend/boot_test.go`. Every
+`daemonAPI` field is set on a fully wired deployment. The handler gets the API
+it was built with. The worker set is asserted by name, at the full set and at
+the floor.
+
+Still by hand: unlock a locked box by passkey, ask something that needs Nexus,
+and check `/tools` lists the MCP servers.
+
 ## What is wrong
 
 `run()` in `cmd/mavend/main.go` brings the daemon up two ways. A box with a key in the
