An expired session exits 3 with one line saying to run quak login (closes #164)
A 401 from the server that ends a command reaches run in src/cli-run.ts as
an ApiError; run prints one line saying to run "quak login" and exits 3.
quak backup meets it on its first refresh, before it touches any file. For
the commands that load the saved session, a missing or corrupt session file
keeps its message and also exits 3.

Judgement call: quak logout is unchanged; it handles its own errors and
deletes the session file whatever the server answers.
Judgement call: quak backup still prints its two progress lines before the
error line.

// The CLI's commands as plain functions.
//
// Each command takes its options and a `CliContext` and resolves to the exit
// code; a thrown error is left to the caller. Nothing here calls
// `process.exit`: `bin/quak.ts` wires these to the command line, and `run` in
// `cli-run.ts` prints a thrown error as one line and exits once output has
// drained. Output must stay byte-identical (see `cli-output.ts`).
