PR Summary

Medium Risk
Adds a new Sim API surface in the CLI and modifies the installer to run interactive prompts, which could affect automation/non-interactive installs and user workflows.

Overview
Adds a new dune sim evm activity <address> command that calls /v1/evm/activity/{address} and supports filtering (--chain-ids, --token-address, --activity-type, --asset-type) plus pagination (--limit, --offset) with table or JSON output.

Extends sim evm to register the new subcommand and adds integration-style tests covering text/JSON output, filters, and pagination.

Updates install.sh to optionally run an interactive post-install flow (when /dev/tty is available) that offers to install the Dune AI skill via npx and optionally runs dune auth; otherwise it prints non-interactive tips.

Hardcoded "ETH" symbol wrong for non-Ethereum chains

Medium Severity

The activitySymbol fallback for AssetType == "native" always returns "ETH", but the activity command supports querying any EVM chain via --chain-ids. For chains like BSC (BNB), Polygon (MATIC/POL), or Avalanche (AVAX), native transfers without token_metadata will incorrectly display "ETH" as the symbol in the text table output.
