add error log, identify the abnormal key

Why is it necessary to schedule this operation every 30 minutes? or this crontab expression should be configurable.

skip the offline model or broken model？

check every time of startCron or every time of schedule？

…el config and scheduler

Copilot

Pull request overview

Adds model-level configuration and a built-in scheduler to automatically build segments on a daily schedule, and exposes the configuration through REST + Kystudio UI so users can configure/observe auto scheduled builds per model.

Changes:

Introduces AutoSegmentBuildConfig and wires it into SegmentConfig, project defaults, model config request/response, and open API mapping.
Adds AutoBuildSegmentScheduler to periodically dispatch scheduled segment build jobs using project time zones.
Extends ModelBuildService to support scheduler-triggered incremental segment builds with a configurable submitter, plus unit tests for validation and scheduler behavior.

Add a project-level dispatcher switch and evaluate the latest due schedule cycle on each scan. Handle covered, overlapping, blocked, and retryable segment build states by target range.
