Applies connector-specific additions from feat/connectors-soul:
- chat.el: connector_tools_json(), agentic_tools_all(), call_mcp_bridge(),
tool_auto_approved() and mcp__ dispatch in dispatch_tool()
- routes.el: connectd_get/post, handle_connectors(), /api/connectors routing
in GET and POST sections
- MEMORY_RECALL_BUG.md: investigation notes on memory retrieval failure
The agentic loop rewrite in the source branch was not applied — it conflicts
with the tool-bridge pattern from PR #5 which is the chosen design for
client-side MCP tool execution. The connectors themselves are now fully
wired: connector tools surface as mcp__<server>__<tool> in the tools array
and dispatch to neuron-connectd via call_mcp_bridge().
