feat(swe): add baseagent-echo testing with harness fixes (#12)

Test the baseagent-echo agent (echobt/baseagent-echo) against 9 SWE-bench
tasks from the validated-dataset (3 easy, 3 medium, 3 hard) using the
swe-forge Docker harness. Results: 2/2 resolved on tasks with valid
sanity checks (100% effective resolution rate).

Harness fixes in src/swe/harness.rs:
- Pass OPENROUTER_API_KEY env var into Docker containers so the agent
  can authenticate with OpenRouter for LLM calls
- Install python3/pip/venv in all containers (not just Python-based ones)
  since the agent itself requires Python regardless of task language
- Add --break-system-packages flag to pip install for requirements.txt
  to work on Debian-based images without virtualenv conflicts
- Support DOCKER_AGENT_DIR env var override for agent directory path
  resolution in nested Docker environments
- Increase system tools install timeout from 120s to 180s

Build config change in .cargo/config.toml:
- Switch linker from clang+mold to cc for broader build compatibility

Test results in agent-tests/:
- Per-task JSON results organized by difficulty (easy/medium/hard)
- Execution logs for resolved tasks (batocera.linux-15418, happier-35)
- summary.json with aggregate metrics
- README.md documenting methodology and findings
- 5 tasks failed sanity checks (dataset issues), 2 had setup errors

Added baseagent-echo as embedded git repo for local testing.

+
+## Status Definitions
+
+- **resolved**: Agent successfully fixed the issue; all tests pass.
+- **sanity_fail**: The task's sanity checks failed on the base commit (tests don't behave as expected before the agent runs). This is a dataset/environment issue, not an agent issue.
+- **setup_error**: The task's repository could not be cloned or checked out. Infrastructure issue.
+- **agent_error**: The agent crashed or timed out. (None occurred.)
+
+## Key Findings
+
+1. **The agent works correctly.** On every task where the sanity checks passed (2/2), the agent resolved the issue successfully.
+2. **5 tasks have sanity check failures.** The pass-to-pass or fail-to-pass test expectations don't match the actual behavior on the base commit. These are dataset validation issues.
+3. **2 tasks have setup errors.** Repository checkout failures (shallow clone issues, missing commits).
