INSERT_DATE is now a SCHEDULE event using KEY=VALUE attributes, and the file
format version is bumped to SIMEVENTS 1.2:
<date-expr> INSERT_DATE [EVERY=<duration>] [UNTIL=<date-expr>]
- EVERY takes a duration literal, DURATION variable or expression
(EVERY=1mon, EVERY=30d, EVERY=12mon, EVERY=12h) and must be positive.
Occurrence n is start + n months (clamped), then + n times the fixed part,
which preserves the dates of the previous DAY/MONTH/YEAR recurrences.
- UNTIL is an inclusive end date and requires EVERY; quote values with spaces.
- COMMENT is accepted and ignored; other attributes are rejected.
- SIMEVENTS 1.1 files and old-style INSERT_DATE lines are rejected with a
migration hint showing the rewritten line.
