/**
 * Regression: clicking the "currently selected" Project in the Project dropdown must not clear
 * the Agent list and the Sessions under it.
 *
 * Old bug: setCurrentProjectId unconditionally called setAgents([]) + setAgentsLoading(true),
 * while currentProjectId itself didn't change — reloadAgents' effect depends on it and wouldn't
 * re-run, so the sidebar's Agents and the Sessions hanging under them would all disappear and
 * never come back (reproducible by simply clicking the current Project in the dropdown).
 *
 * A Project is deliberately created with a display name different from the username: a newly
 * registered user's initial Project display name defaults to the username, and the bottom-left
 * user menu also shows the username, so locating by name would match both.
