feat(definitions): propose Binky operating-rhythm definitions (disabled)

Three proposed, disabled definitions for the binky-control rhythm
(BINKY-WP-0003-T05): daily rhythm, weekly paper-mail intake, weekly
founder-review prep. All parse via definition_parser. Enabling requires
the proposed binky_rhythm_status state-hub resolver and an executor
(llm-connect assessment, BINKY-WP-0003-T06).
