docs: add developer quickstart

[vamshi4001]

Summary

• add a Developer Quickstart page for builders integrating Aerodrome on Base
• link to canonical protocol and Slipstream deployment tables
• include minimal viem examples for pool discovery, metadata reads, and basic route quotes
• add an integration checklist covering route type detection, slippage, deadlines, decimals, and staking/deposit flow safety

Testing

• yarn --ignore-engines lint
• live viem sanity check against Base public RPC for WETH/USDC pool discovery, metadata(), and Router.getAmountsOut

Note

• yarn --ignore-engines build exits 0 locally, but Island/Vite prints missing dependency errors for existing SVG-based pages (@babel/preset-react, react-inlinesvg). I left package metadata unchanged because this PR is docs-content only.

Happy to adjust this to match your preferred developer patterns.
