Add safe condition checks

[bnvnvnv]

Summary

Add a safe select option and extend safe condition validation to avoid accidental full-table operations when upstream passes empty parameters.

• add safeSelect configuration and wire it into object and Example select providers
• require object-based CRUD safety checks to have at least one effective WHERE condition
• make Example safety checks reject empty condition values, including null, empty string, empty collection, and empty array
• cover tk.mybatis Example and generated Example styles in tests

Validation

• mvn -pl base -am -Dtest=SafeSelectByFieldTest,SafeDeleteByFieldTest,SafeDeleteByMethodTest,SafeUpdateByFieldTest,SafeUpdateByMethodTest -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false test
• mvn -pl base -am -DfailIfNoTests=false test
• git diff --check

Pull request overview

This PR introduces a new safeSelect configuration and strengthens “safe” condition validation across object-based and Example-based CRUD operations to prevent accidental full-table reads/updates/deletes when upstream passes empty parameters.

Changes:

• Add safeSelect to configuration and enforce it in object-based select providers and Example select providers.
• Strengthen safety checks to require at least one effective condition (including rejecting empty strings/collections/arrays where configured).
• Extend/adjust tests to cover empty-condition rejection for delete/update/select (including tk.mybatis Example and generated Example styles).
