feat: add Agentic Bets skill

[viraj124]

Summary

Adds AgenticBets skill for placing prediction bets on token prices on Base.

AgenticBets is a binary prediction market on Base:

• Bet UP or DOWN on token prices with USDC (5-min rounds)
• Live markets for AGBETS, CLAWD, MOLT, WCHAN, and more Bankr-ecosystem tokens
• Winners split the pool pro-rata (2.1% total fee — 1.5% treasury / 0.5% creator / 0.1% settler)
• Transactions go through the Bankr Wallet API (POST /wallet/submit) — no local keys, no custom RPCs
• Works for any agent: place bets, check odds, list open markets, claim winnings, all via natural language

Prediction → Execute Pattern

AgenticBets slots directly into Bankr's agent workflow:

Markets API (Research)       Bankr Submit (Execute)
──────────────────────      ──────────────────────
Live pool size + odds   →   Approve USDC + bet()
Round status / timing   →   Place UP or DOWN bet
Claimable winnings      →   claim() settled epochs

All on-chain actions are signed by the user's Bankr wallet — no API key management beyond the standard Bankr key.

Quick Start

# 1. Install Bankr CLI and log in (write-access key required for bets)
bun install -g @bankr/cli
bankr login email you@example.com --read-write

# 2. Use the skill
scripts/agenticbets.py list open             # See open markets
scripts/agenticbets.py odds AGBETS           # Current UP/DOWN split + pool
scripts/agenticbets.py bet AGBETS up 5       # $5 UP bet
scripts/agenticbets.py claim AGBETS 42       # Claim settled epoch

Or just ask the agent: "Bet $5 UP on AGBETS" / "What prediction markets are open?" / "Claim my AGBETS winnings from epoch 5".
