/**
 * `emdash-plugin switch <did>`

 * Change the active publisher session. The DID must already be in the
 * credentials store (i.e. you've previously logged in as it). Use
 * `emdash-plugin whoami` to see stored sessions.
 *
 * The OAuth library still resolves a refreshed access token by DID on the
 * next publish; this command only changes which DID is "current" for the
 * convenience of subsequent commands.
