fix: doc_query chronological insert, register cli/webui output channels

- context.go: add InsertByTimestamp for chronological context insertion
- toolcall.go: doc_query uses InsertByTimestamp instead of Append
- agent_tools_test.go: update tests to use payload/type keys
- cli/plugin.go: register output_send__cli channel
- webui/plugin.go: register output_send__webui channel
