[devin-ai-integration]

Summary

• Version bump 1.4.1 → 1.5.0 in pyproject.toml + uv.lock (same shape as the v1.4.x release bumps).
• Sandbox image tag bump strix-sandbox:1.2.0 → 1.3.0 everywhere it's pinned (strix/config/settings.py RuntimeSettings.image default, scripts/install.sh pre-pull, docs/advanced/configuration.mdx), picking up the Dockerfile changes since 1.2.0 (govulncheck + golang-go added in 97336d5).
