Refresh README hero and add artifact-backed benchmark snapshot

[ProfRandom92]

Motivation

• Remove decorative/broken header graphics and present a compact, enterprise-ready text-first hero that communicates scope and trustworthiness quickly.
• Surface deterministic, auditable benchmark values from committed artifacts so reviewers can validate claims without running external services.
• Make integrity and limitation boundaries explicit (no LLM judging, no embeddings, no external APIs) to improve auditability for enterprise reviewers.

Description

• Replaced the image-first header with a text-first hero and concise positioning lines: # Comptextv7 and the one-line descriptor; removed decorative and dead image markup. The only modified file is README.md.
• Added concise badges sourced from the repository and shields.io for Python and CI, and static badges for Deterministic Replay, No LLM Judging, Replay Artifacts, and Operational State.
• Inserted an artifact-backed benchmark snapshot populated from artifacts/paper_replay_results.json and artifacts/agent_trace_replay_results.json (paper: 3 papers, avg_compression_ratio 1.347063, replay_consistency 0.791667; agent: 3 traces, avg_compression_ratio 1.773954, replay_consistency 1.000000, operational_drift 0.000000).
• Added the requested Mermaid architecture diagram, a compact What exists now capability table, an Integrity model section describing determinism and auditability, and a short Limitations section that remains factual and non-hype.

Testing

• Ran the project continuity test python -m pytest tests/test_replay_continuity.py which completed successfully (8 passed).
• Ran an automated README verification script that confirmed the benchmark values in README.md match the committed JSON artifacts and confirmed decorative image markup was removed, and that check passed.
• No other code changes were made, so repository CI workflows remain unchanged and were not modified by this PR.

Code Review

This pull request significantly refactors the README.md to focus on deterministic operational memory and CI-audited replay checks, removing extensive research-oriented descriptions in favor of a concise benchmark snapshot and integrity model. A review comment identifies a potential inconsistency regarding the project's limitations, noting that the document lists iterative replay degradation as a future target despite existing reports covering up to 250 iterations.

[gemini-code-assist]

The limitation "Iterative replay degradation is the next validation target" appears to be inconsistent with the "Primary replay-continuity benchmark" described later in the document (line 73) and the results already present in reports/replay_continuity/validation_report.md, which explicitly covers up to 250 iterations. If this limitation refers to a specific subset of benchmarks (e.g., the Paper or Agent Trace benchmarks) or a higher scale of iteration, please clarify it to avoid confusing reviewers.
