Add a JSON-based skills specification system that allows users to define
custom tools loaded by the experimental agent loop. Skills are auto-discovered
from standard locations (./ollama-skills.json, ~/.ollama/skills.json,
~/.config/ollama/skills.json).
Features:
- SkillSpec schema with parameters and executor configuration
- Script executor that runs commands with JSON args via stdin
- /skills reload command for runtime skill reloading
- Comprehensive validation and error handling
