Overview
Updates Agent Wallet documentation for CLI v5.2.0, including the skills compatibility note in the quickstart (v5.1.0 → v5.2.0).

Swaps: Documents that mm swap quote can return a soft unavailable result (exit 0) with kind: "unavailable", reason, message, and hint when the bridge has no routes for actionable reasons (AMOUNT_TOO_LOW, SLIPPAGE_TOO_HIGH, NO_QUOTES, etc.). Only QUOTE_RETRY is documented as a hard error (exit 1). Guides, command reference, troubleshooting, and swap pitfalls are aligned with this behavior.

Prediction markets: Documents optional --tick-size on mm predict quote and mm predict place, including allowed values and default-to-CLOB behavior.

Error codes & troubleshooting: Adds WALLET_NOT_REGISTERED, QUOTE_RETRY, PREDICT_INSUFFICIENT_GAS, and INVALID_TICK_SIZE, plus guidance to fund POL on Polygon when predict deposit fails for gas.
