feat: add OpenHands harness support to metrics extractor

sjarmak · claude · sjarmak · commit f11742f894a1 · 2026-03-07T17:39:25.000Z
- Detect harness type (OpenHands vs Claude Code) from agent output
  files and result.json config.agent.import_path
- Extract tokens from trajectory.json final_metrics (OpenHands) when
  claude-code.txt transcript is unavailable
- Add OpenHands tool names to _LOCAL_TOOLS (execute_bash,
  str_replace_editor, read_file, think, finish, task_tracker)
- Add OpenHands MCP tool names to _OPENHANDS_MCP_TOOLS and
  _SEARCH_TOOL_MAP (keyword_search, list_repos, etc.)
- Handle str_replace_editor in code changes extraction (create,
  str_replace, insert commands)
- Add agent/openhands.txt to transcript candidate paths

Tested: 24/25 OpenHands staging tasks now extract full metrics
(tool_calls, tokens, code changes, search patterns). Only failure
is the envoy task where agent never ran (expected).
Claude Code extraction unchanged (regression tested).
