Subject: [PATCH] feat(cli): add `call` command for arbitrary contract calls
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds `polygon-agent call --to <addr> --data 0x... [--value <amount>]
[--wallet <name>] [--chain <name|id>] [--prefer-native-fee]
[--broadcast]`, a thin wrapper over the existing runDappClientTx
primitive that submits any pre-encoded calldata through the active
wallet session. Users encode function calls with viem/ethers/cast
and hand the calldata to the CLI directly, no domain-specific
helpers required.

Default gas-payment path mirrors the rest of the CLI: pay in an
ERC20 fee token (USDC etc.). Pass --prefer-native-fee to use the
chain's native token (POL/ETH) instead — useful when the wallet has
only native
