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.

Task 01 changes bxcore's wire and log types for M5c-1: Turn.speaker and
LogRecord::User.speaker (optional, skipped when None, so old frames and logs
keep their bytes), SessionUpdated.turn (required, refused when missing), and
the new SessionState / SessionStateReply messages. The other crates only
construct the new fields (speaker: None, turn: 0) and brokerd's kind() names
the two new kinds; later tasks give them values. 20 given files.
Checks, against a reference at 7b40686 with its own build directory:
- every "before" block found exactly once at 7b40686 (and at master, which
changed no crate since);
- step 2's failures as the task names them: two strict tests, fifteen test
targets with E0559/E0560/E0432/E0599 only;
- make gate: gate: ok, 1130 tests (1122 + 8); /tmp unchanged around it;
- replay from the task text in a fresh worktree of 7b40686 with its own
target/: crates/ byte-identical to the reference, gate ok, 1130; removed;
- 23 mutations: 21 caught; the two that drop `default` from an Option
field cannot change behaviour (serde reads a missing Option as None);
- no chat-template tag whole in the task or the given files; lines over
100 characters only in tables, fixtures and verbatim strings.
