docs: add AI-assisted documentation disclaimer

[EsOsO]

Summary

Added transparency disclaimer to both README and documentation homepage to clarify the nature of AI-assisted content while emphasizing manual review of critical infrastructure code.

Changes

README.md:

• Added NOTE callout after main header
• Clarifies documentation is AI-assisted
• Emphasizes Docker Compose and infrastructure code are manually written/reviewed

docs/index.md:

• Added similar disclaimer as MkDocs admonition
• Positioned after "What is Omakase?" info box
• Consistent messaging with README

Rationale

Provides transparency to users about:

• ✅ Which content is AI-assisted (documentation/guides)
• ✅ Which content is manually reviewed (Docker Compose, service configs, infrastructure code)
• ✅ Emphasis on security and reliability through human verification

This builds trust by being upfront about the use of AI while reassuring users that critical infrastructure configurations receive thorough human review.
