 * How long a request may go quiet before bun closes the connection under it.
 *
 * This is the HTTP inactivity timeout, not the socket's: the socket's own lives
 * on the `websocket` handler object and defaults to two minutes, which bun's
 * automatic pings keep resetting. Setting a value at this level does nothing
 * for the page's socket at all.
 *
 * It is bun's maximum because one handler here waits on a person rather than on
 * a computer: `POST /api/pick` opens a native folder picker and does not answer
 * until somebody has chosen a directory. bun's default of ten seconds closes
 * the connection under exactly that. Measured on bun 1.3.14: a handler that
 * takes fourteen seconds is cut off at ten and the caller's fetch rejects with
 * "the socket connection was closed unexpectedly". node's server, which this
 * replaced, imposed no such limit, so leaving this unset is a regression rather
 * than a default.
 *
 * Exported so the floor can be asserted: what matters is not the exact number
 * but that it is far longer than a person takes to pick a folder.

 * launch directory is that somewhere else.
 *
 * A project with no config gets one, rather than the refusal `ensureProjectConfig`
 * gives a verb that is about to go and look at something: this is the screen a
 * person configures a project ON, so stopping here to ask them to edit a file
 * and re-run is the wrong shape. A directory that is no project at all is
 * refused instead of littered.
