fix: clarify cron reminder wording (#1204) (thanks @cpojer)

CHANGELOG.md

@@ -13,18 +13,13 @@ Docs: https://docs.clawd.bot
 - Signal: add typing indicators and DM read receipts via signal-cli.
 - MSTeams: add file uploads, adaptive cards, and attachment handling improvements. (#1410) Thanks @Evizero.
 
-### Breaking
-- **BREAKING:** Envelope and system event timestamps now default to host-local time (was UTC) so agents don’t have to constantly convert.
-
 ### Fixes
 - Config: avoid stack traces for invalid configs and log the config path.
 - Doctor: warn when gateway.mode is unset with configure/config guidance.
-- OpenCode Zen: route models to the Zen API shape per family so proxy endpoints are used. (#1416)
 - macOS: include Textual syntax highlighting resources in packaged app to prevent chat crashes. (#1362)
 - Cron: cap reminder context history to 10 messages and honor `contextMessages`. (#1103) Thanks @mkbehr.
-- Exec approvals: treat main as the default agent + migrate legacy default allowlists. (#1417) Thanks @czekaj.
+- Cron: clarify reminder systemEvent wording guidance. (#1204) Thanks @cpojer.
 - UI: refresh debug panel on route-driven tab changes. (#1373) Thanks @yazinsai.
-- UI: export config form section metadata for shared usage. (#1418) Thanks @MaudeBot.
