Add AVOS v0.3: configurable auto-iteration UI, CLI, docs and convergence logic

[dannyling111]

Motivation

• Introduce a configurable autonomous iteration flow (5–20 rounds) and an automated convergence check to avoid blind multi-round runs.
• Provide both a browser UI and a CLI so iterations can be run interactively or in scripts for MVP validation.
• Ship project documentation and a local Pages-friendly redirect so the MVP is easy to run and review.

Description

• Add a single-page front-end app/index.html implementing the configurable iteration UI, scoring/critique/revise logic, Markdown report/copying, and a convergence suggestion engine.
• Add a CLI runner scripts/autopilot_iterate.py implementing the same propose/score/critique/revise loop, Markdown rendering, and --rounds/--topic arguments.
• Add docs and metadata: top-level README.md, project docs under docs/ (00_project_brief.md through 05_pages_setup.md), a run summary docs/04_run_summary.md, and a root index.html that redirects to app/index.html for Pages/local hosting.
• Implement core scoring, critique, and revision heuristics with a convergence/advice heuristic to recommend whether to continue iterations or switch to data-driven optimization.

Testing

• No automated tests were configured or run for this PR.
