CLI-08: Lean on auto-discovered config

What it demonstrates

With a markdown-contract.yaml in the working dir, validate routes each glob to its contract with no flags.

Builds on: CLI-05: Validate a whole directory

How it’s done

The declarative YAML artifact, verbatim — no code required.

# markdown-contract.yaml (auto-discovered from cwd)
mcVersion: 1
kind: config
contracts:
  decisions: ./contracts/decisions.contract.yaml
  tasks: ./contracts/tasks.contract.yaml
rules:
  - include: ['decisions/**/*.md']
    contract: decisions   # first matching rule wins
  - include: ['tasks/**/*.md']
    contract: tasks

Surfaces exercised

• auto-discovery of markdown-contract.yaml
• kind:config
• contracts map + rules (globs→contract, first match wins)
• loadConfigFile
