feat(core): support ACL and JSON config formats in Agent.create

claude · claude · commit 3852883cf835 · 2026-04-20T17:34:41.000+08:00
- Add CodeConfig::from_acl() to parse ACL (Agent Configuration Language)
- Update Agent::new() to detect .acl files and inline ACL strings
- Agent.create now accepts HCL, ACL, JSON, or .acl/.json file paths
- SessionManagerService generates JSON config instead of HCL
- Fix test compilation: add missing CancellationToken to complete_streaming
- Fix incorrect tests: agentic_search/agentic_parse are skills, not tools
