Claude Code rejects `defaultModel` in plugin.json and `model` in agent
frontmatter with "Unrecognized key" validation error.
Removed:
- defaultModel from 6 plugin.json files
- model from 7 agent frontmatter files
- docs/MODEL-RECOMMENDATIONS.md (deleted)
- Model config sections from CONFIGURATION.md and CLAUDE.md
- Model validation from validate-marketplace.sh
This reverts Sprint 7 (v5.4.0) multi-model feature that was never
supported by Claude Code's plugin schema.

Add 2 autonomous agents:
- full-validation: Complete cross-plugin compatibility validation
triggered by /validate-contracts command
- agent-check: Single agent definition validation triggered
by /check-agent command
Each agent documents capabilities, workflow, validation rules,
and example interactions.
