Complete interview-ready InsightFlow showcase

[hachiwar]

What changed

• completed DataAgent SQL governance, bounded repair, result verification, question-aware answers, and audit records
• redesigned the GitHub Pages site with fixed left navigation, responsive content sections, and the runnable multi-table data lab
• rewrote README, architecture, Java service, GitHub Pages, and domestic server deployment documentation
• removed PDFs, interview notes, resume drafts, and the implementation-status document from repository tracking; local preparation files remain ignored
• added Python and Java regression tests for policy enforcement and the MindAgent-DataAgent answer contract

Why

This makes the repository suitable for an interviewer to review directly while keeping personal preparation material local and ensuring the claimed data path is runnable, testable, and safe by default.

Validation

• Python: 4 tests passed
• Java: 3 tests passed
• Frontend: 5 tests passed and Vite production build succeeded
• Docker Compose configuration parsed successfully
• Browser QA: desktop and 390px mobile layouts, navigation, two complex data scenarios, question-aware explanation, and DELETE rejection
