Contract bug (2026-08-04): the cronjob tool schema documents '30m' as
'(every 30 minutes)' — recurring — but parse_schedule returned
kind='once' for bare durations, silently creating a one-shot job for a
recurring request (agent passed '30m' for 'every 30 min', job ran once
and died). Bare durations ('30m','2h','1d') now parse as recurring
intervals matching the documented contract; explicit one-shot by
duration is 'in 30m'/'in 2h' (fires once that far from now). ISO
timestamps stay one-shot.
Also fixes the sibling repeat-coercion class (#66824/#64520/#7142):
repeat='forever'/'once'/'N' strings now coerce in create_job instead of
raising "'<=' not supported between instances of 'str' and 'int'".
Tool description rewritten to teach the corrected contract and steer
relative requests to 'in Nm' (no more hand-computed ISO timestamps).
Supersedes the doc-only direction of #53739 while keeping its goal
(relative one-shots must be expressible) via the 'in X' form.
