- Simplify `.ocamlformat` to use `default` profile with fewer overrides - Extract shared types and utilities into a `remind_sync` library (`icalendar_augmented`, `ptime_augmented`, `timedesc_augmented`, `result_augmented`, `utf8`) - Replace `eventTransformer.ml` and the predicate system in `eventPredicates.ml` with a sequential collector pipeline (`collect_uuid`, `collect_summary`, `collect_start_end_duration`, etc.) - Simplify `Remind.rem` to a flat record with `Timedesc` date/time fields and replace `rem_to_string` with a leaner `string_of_rem` - Add `separate_master_and_recurrence` and `get_recurrence_id` helpers to `utils.ml` - Wire `main.ml` to call `EventPredicates.remind_of_event` per UID group and print results directly - Remove `eventTransformer` module from `bin/dune` and enable the `remind_sync` library dependency
