What does this PR do?

Raises the default auxiliary compression timeout from 120s to 300s so large Codex/compression passes are less likely to self-timeout and get retried as noisy connection failures.

Type of Change

• 🐛 Bug fix (non-breaking change that fixes an issue)
• ✨ New feature (non-breaking change that adds functionality)
• 🔒 Security fix
• 📝 Documentation update
• ✅ Tests (adding or improving test coverage)
• ♻️ Refactor (no behavior change)
• 🎯 New skill (bundled or hub)

Changes Made

• increased DEFAULT_CONFIG["auxiliary"]["compression"]["timeout"] from 120 to 300
• clarified the inline config comment so the longer timeout is explicitly tied to large-context / slower cloud backends
• added a regression assertion for the default timeout in tests/hermes_cli/test_aux_config.py
• updated the reset-preserves-timeouts expectation to the new default

How to Test

1. Run uv run --frozen pytest -q -o addopts='' tests/hermes_cli/test_aux_config.py
2. Confirm DEFAULT_CONFIG["auxiliary"]["compression"]["timeout"] == 300
3. Run hermes model / reset-aux flows and confirm compression timeout stays at the new default unless a user has overridden it
