The speaker goes on every turn of the chat: interactive, --say and --say's retry. Without the
flag it is None. A name that is empty or holds whitespace or a control character (Unicode), or a
second --speaker, is a usage error: the usage text on stderr and exit status 2. The usage text
gains the flag and one line explaining it. Given: chat_speaker.rs (new) and new versions of
chat.rs, chat_approvals.rs and cli.rs. Task 01 now copies chat.rs-task01, the older chat.rs.
Checks: every before block found once at ref 03; replayed from the task text on a fresh ref-03
worktree with its own build directory, byte-identical to the reference, gate ok with 1158 tests
(1148 + 10); /tmp unchanged around the reference's and the replay's gate runs; 20 of 20
mutations caught; the new tests passed 40 of 40 runs under CPU load; given files pass fmt and
the 500-line check; no chat-template tag in the plan or the given files.
