Summary

Follow-up documentation cleanup. The previous documentation PR (#15) has already been merged with the full-length files in the repository root; this PR moves those documents into a dedicated docs/ folder.

Proposed structure

• README.md (root): concise repository landing page linking to the documentation.
• docs/README.md: full project overview, problem statement, tech stack, demo URL, local installation, endpoint summary, and team.
• docs/PROJECT_BUILD_AND_ARCHITECTURE.md: detailed end-to-end architecture and component guide.
• docs/AWS_DEPLOYMENT_AND_OPERATIONS.md: AWS deployment and operations runbook.

Safety and accuracy

• Updates relative Markdown links for the new folder locations.
• Preserves the PostgreSQL volume safety reminders.
• Keeps the current demo URL clearly marked as HTTP.
• Retains the distinction between local and production Compose services and the known CI/CD SSH connectivity blocker.
• Documentation-only: no application source, Compose configuration, GitHub Actions workflow, AWS resource, or production data is intentionally changed.

Review note

Review the file moves and links before merging. The previous PR (#15) is already merged; this PR contains the additional folder organization.
