fix(tmux-context): contain executor rejection as a warning, correct suppression claim

Review round on #758.

bash.run() only promises to resolve for nonzero exits, timeouts, and aborts,
and bash.resolve() can reject on policy grounds, so either could escape the
serial agent/step listener and abort the model turn — contradicting the
plugin's documented failed-query no-op contract. Contain both and log a
warning instead; the location is optional context.

The Agent Note claimed an unchanged location suppresses the query. It does
not: only the interval floor is checked before the query, while change
suppression compares state the query returned. Corrected in both languages
and re-recorded the i18n pairs.
