[next-wave] Add 'sanctified' SVG badge generator with on-chain verification

[Gbangbolaoluwagbemiga]

Context

Contracts that pass Sanctifier static analysis AND have an active Runtime Guard Wrapper on-chain should be able to render a verifiable badge for their README.

Design

[ Sanctified ✓ ] [ runtime-guard active ] [ 142 calls · 99.3% pass rate ]

The badge data is queried live from the on-chain Runtime Guard Wrapper.

Tasks

• New subcommand: sanctifier badge --contract <ADDR> --output badge.svg
• Call get_stats on the supplied wrapper contract via Soroban RPC
• Render an SVG with computed pass rate, total calls, last-call timestamp
• Host a Vercel edge function at /api/badge/[contract].svg that serves the same badge dynamically
• Add badge to LIVE_TESTNET.md
• Documentation page in /docs

Acceptance Criteria

• Badge SVG renders cleanly in GitHub README (no broken refs)
• Live edge endpoint responds in <500ms cold start
• Badge updates within 1 minute of a new recorded call on-chain
