Add Solana launch readiness skill

[ashalafan]

Summary

Adds solana-launch-readiness-skill, a safety-first agent skill for pre-launch Solana dApp review.

Why this is useful

This fills a practical gap between generic Solana coding skills and formal audits: founders and builders often need a fast structured launch-readiness scan before mainnet. The skill guides agents through wallet integration, transaction flow, RPC/env separation, frontend/backend trust boundaries, error handling, logging, build/deploy readiness, and launch blocker reporting.

Safety positioning

• Not a formal smart contract audit
• No seed phrases, private keys, production wallet access, or real customer data
• No live mainnet deployment or fund-moving actions without explicit human approval
• No exploit/bypass work

Contents

• SKILL.md entry point
• Safe install.sh with no network calls and no sudo
• Launch-readiness report template
• Wallet, transaction-flow, and env/RPC/mainnet checklists
• Reusable prelaunch/risk-scan prompts

Validation

• bash -n install.sh passed
• install script copied 9 expected files into a temp skill directory
• Public standalone repo: https://github.com/ashalafan/solana-launch-readiness-skill
