Production v0.18.1 logs showed read_message → "did you mean: send_message"
— two edits away by Levenshtein, but the opposite intent. An agent asking
to READ a single message getting nudged toward SEND is actively
misleading. Same trap was active for anything sharing a verb-less suffix
like _message, _channel, _task.
Constrain the Levenshtein candidates to those whose leading verb (token
before the first underscore) matches the input verb exactly. Substring
matching is unchanged. Drop the now-stale sned_message typo test case
(cross-verb typo correction is no longer in scope) and add a regression
test covering read_message, delete_message, fetch_channel.
