Add ReadMe Sync Workflow

Summary

Automatically sync 3 documentation pages from GitHub → ReadMe using GitHub Actions.

Why This Approach?

Evaluated two options:

Option 1: ReadMe Built-in Git Sync (Bi-directional) ❌

• Pros: Bi-directional sync (edit in GitHub or ReadMe)
• Cons:
  • Syncs ALL ReadMe content (~20+ pages) to the repo
  • Creates docs/ folder with duplicate content
  • Adds complexity with _order.yaml files and category folders
  • Mixes code examples with comprehensive documentation

Option 2: GitHub Actions with rdme CLI (One-way) ✅ CHOSEN

• Pros:
  • Selective sync (only 3 files)
  • Clean repo (one workflow file)
  • GitHub as single source of truth
• Cons:
  • One-way only (GitHub → ReadMe)
  • Must edit in GitHub, not ReadMe

What This Does

Syncs these 3 files to ReadMe on every push to main:

GitHub File	ReadMe Page
how_to/HOW_TO_FUND_SXT_CHAIN_ACCOUNT.md	Fund your wallet's SXT Chain account
tutorials/create_hello_world_table/README.md	Creating Tables (DDL)
tutorials/onchain_hello_world_query/README.md	Queries from a Smart Contract
