Pull request overview

This PR adds an opt-in mechanism to resolve agent name / display_name conflicts during agent imports, and enables it specifically for marketplace (agent repository) imports to prevent duplicate-name collisions that block publishing and can misroute “edit” flows that rely on unique agent names.

Changes:

• Add resolve_name_conflicts plumbing through import_agent_impl(...), import_agent_by_agent_id(...), and import_agent_with_skills_impl(...).
• When enabled, automatically suffix-conflict agent name and display_name (e.g., _1) before creating the imported agent.
• Extend service tests to assert the flag is passed for repository imports and verify suffixing behavior.

• Same as agent_name: if display_name suffix generation hits max_suffix_attempts, the resulting error lacks any context (which display_name/tenant caused it). Re-raise with the base display_name and tenant_id so the failure is diagnosable.

            agent_display_name = _generate_unique_display_name_with_suffix(
                agent_display_name,
                tenant_id=tenant_id,
                agents_cache=agents_cache,
            )
