feat: add agent guidance and memory system for v0.6.0 (#13)

* feat: add agent guidance and memory system - enable collaborative development

Why: Establish foundation for agent-assisted development with persistent context
Approach: Adapted otlp-mcp's BOTS.md guidance to otel-cli's philosophy
Learned: otel-cli's functional testing approach and self-contained design are key differentiators
Next: Use GitHub issues to track ongoing work and maintain visibility

Added:
- BOTS.md with otel-cli-specific agent guidance
- CLAUDE.md and GEMINI.md symlinks for model-specific access
- Emphasis on functional testing over unit tests
- Git-based memory system (vs jj in otlp-mcp)
- GitHub issues integration for project tracking

This marks v0.6.0, the beginning of the agent-assisted development era.
