Changelog summary ([0.1.23])

Added

• working_dir for LLM agents and their MCP servers (feat(working-dir): working_dir for LLM agents and their MCP servers #297)
• runtime.tool_output limits for oversized MCP tool results (feat(providers): add runtime.tool_output limits for oversized MCP tool results #313)
• Inline expand/collapse for subworkflows in the dashboard graph (feat(web): inline expand/collapse for subworkflows in the dashboard graph #316)

Fixed

• Subworkflow-adjacent agent node could appear stuck "running" in the dashboard (fix(web): clone subworkflowContexts tree in processEvent (#307) #308)

Validation

• make check ✅ (lint + format + ty; one pre-existing unrelated ty warning in dialog_evaluator.py)
• make test ✅ — 4160 passed. The only failure was the opt-in real_api live test (test_copilot_large_write) pinned to the unavailable internal model claude-opus-4.7-1m-internal; re-run with an available model (claude-opus-4.8) it passes (7m40s). Release CI runs pytest -m "not real_api and not performance".
• make validate-examples ✅
