/**
 * pop user join — join an org via QuickJoin, registering a username first
 * when needed.
 *
 * P0 fix (verified contracts origin/main src/QuickJoin.sol): quickJoinWithUser()
 * reads `accountRegistry.getUsername(msg.sender)` and reverts NoUsername when
 * it is empty — the old command advertised --username but never registered it,
 * so fresh accounts always reverted. New flow:
 *
 *   1. Read the username from the SAME registry QuickJoin consults
 *      (quickJoin.accountRegistry() — the authoritative source for this org).
 *   2. Username exists            → one tx: quickJoinWithUser().
 *   3. No username + --username   → two txs: UAR.registerAccount(username),
 *                                    then quickJoinWithUser().
 *   4. No username, no flag, TTY  → prompt for a username, then flow 3.
 *   5. No username, no flag, non-TTY → actionable CliError (exit 1).
 *
 * Pre-flight (skippable with --no-preflight): gas balance always; when
 * registering, checkUsernameFree fails fast (exit 4) if the name is taken
 * (UAR.registerAccount would revert UsernameTaken).
 *
 * Steps 1 and 2 used to be two STRICTLY SEQUENTIAL eth_calls — getUsername
 * could not start until accountRegistry() returned the address to call. Both
 * now come from a single subgraph round-trip
 * (QuickJoinContract.accountRegistry + Account.username), with the eth_calls
 * kept as the fallback. The indexed username is only believed when the
 * indexed account lives on the SAME registry this QuickJoin consults and is
 * not tombstoned; anything else falls through to the live read, so the
 * indexer can never talk this command into the 1-tx path for an account that
 * has no username on-chain.
