Add rhino.fi to Exchanges & Swap Platforms

[Spider333]

What

Adds rhino.fi (app.rhino.fi/bridge) to section 2 with a short "why it's cool" blurb, bumps tool count to 99, updates last-updated stamps.

Why

• Self-custodial cross-chain bridge + swap across 35+ chains (EVM, Solana, Tron, TON)
• No signup, no KYC — wallet-connect only
• Near-instant settlement via pre-funded liquidity network (no slow lock-and-mint)
• Battle-tested team — formerly DeversiFi, building since 2020

Note: pitched on self-custody + no-signup + speed rather than as a privacy tool — rhino.fi doesn't unlink source/destination wallets, so calling it privacy-focused would overclaim.
