Remove mini-SWE shell timeout wrapper

[xeophon]

Summary

• Remove the shell-level timeout wrapper from the packaged mini-SWE-agent command.
• Bump the harnesses package version to 0.1.3 so the fix can be published.

Root cause

The wrapper used GNU-specific timeout --kill-after=30s. BusyBox-based task images reject that option before mini-SWE-agent starts.

Impact

The sandbox API remains responsible for enforcing the command deadline through command_timeout, so mini-SWE-agent no longer depends on a particular timeout binary being installed in the task image. Publishing harnesses==0.1.3 propagates the fix.

Validation

• uv run pytest tests/test_v1_mini_swe_agent.py -q
• direct import check confirmed harnesses.__version__ == "0.1.3"
• Ruff, formatting, Semgrep, and ty pre-push checks passed

This PR intentionally contains only the mini-SWE harness fix and package version bump.

Note

Low Risk
Small harness launch-script change with timeout enforcement still handled by the sandbox API; version bump only.

Overview
Removes the GNU timeout --kill-after=30s wrapper around the packaged mini-SWE-agent launch script so agent startup works on BusyBox-based task images that reject that flag.

The harness now invokes mini directly; execution limits stay with the sandbox command_timeout path rather than a host-specific timeout binary. harnesses is bumped to 0.1.3 for release.

Note

Remove GNU timeout wrapper from MiniSWEAgent command construction

Removes the timeout --kill-after=30s ${AGENT_TIMEOUT_SECONDS:-3600} wrapper from the bash script built in mini_swe_agent.py. The binary now runs directly without an external timeout.

• Behavioral Change: AGENT_TIMEOUT_SECONDS no longer has any effect; the agent process will not be forcibly killed after a timeout period.
• Bumps the harness package version from 0.1.2 to 0.1.3.

Approvability

Verdict: Needs human review

Removes a timeout wrapper that previously limited agent execution to ~1 hour by default. This is a significant runtime behavior change that removes a safety/resource constraint, warranting human review to confirm the intent and implications.
