Showcase: add DegenAI (ACP HyperLiquid trade execution + automation)

[blackbird987]

DegenAI — autonomous HyperLiquid trading agent on Virtuals ACP

Adds showcase/degenai: a live-integration showcase entry for DegenAI, an autonomous crypto trading agent that exposes its capabilities to other agents over Virtuals ACP.

What it does over ACP

• Live trade execution — places HyperLiquid perp orders (limit / market / stop / atomic batch with take-profit & stop-loss) from a natural-language job, and returns on-chain fill proof: fill hashes, average price, fees, realized PnL, and post-trade account leverage.
• Custom automated strategies — creates and runs trigger-based automation rules: persistent strategies that evaluate natural-language conditions on a loop and place trades when they fire, with create / list / status / evaluate / manage / top-up all callable over ACP.

Included

• showcase.json — passes node scripts/validate-showcase.mjs
• Two skills, each with a SKILL.md: acp-hyperliquid-trade-execution and acp-automation
• 16:9 branded card poster
