Add ordeal skill — automated chaos testing for Python

[teilomillet]

Summary

• Adds skills/ordeal/ with SKILL.md teaching AI agents how to use ordeal for Python testing
• Registers the skill in marketplace.json under example-skills

What is ordeal?

ordeal is an automated chaos testing toolkit for Python. It discovers properties, injects faults, runs mutation testing, and explores reachable states. Key capabilities:

• ordeal init — zero-to-validated-tests in one command (mine properties, generate tests, validate with mutations)
• ordeal mutate — mutation testing with gap analysis and test stub generation
• ordeal explore — coverage-guided state-space exploration (AFL-style)
• ordeal audit — mutation score + property coverage + test gap reporting
• Fault injection, chaos testing, differential testing, metamorphic testing

What the skill teaches agents

• Decision tree: which ordeal tool to use for a given task
• CLI commands and Python API with examples
• How to read and interpret results (mutation gaps, coverage reports)
• Key patterns (seed replay, fault ablation, config)

Test plan

• Verify SKILL.md frontmatter follows repo conventions (name, description, license)
• Verify marketplace.json is valid JSON
• Verify skill activates when user asks to test Python code
