Adds hak-ledger-plugin to the third-party plugins list in docs/PLUGINS.md.

What it does: a human-in-the-loop Ledger hardware-wallet signer for Hedera Agent Kit agents — the first Ledger plugin in the HAK ecosystem. A high-risk EVM transaction is Clear-Signed on a physical Ledger before the agent executes it, so the device is the final confirmation gate.

Two tools:

  • ledger_clear_sign — Clear-Sign an unsigned EVM transaction on the device and (optionally) broadcast it. Returns executed / signed / rejected (if the human declines on-device).
  • ledger_get_address — derive + verify a hardware-backed EVM identity.

Pairs with hak-uniswap-plugin's requires_ledger_approval flow: feed its unsignedTx straight into ledger_clear_sign for device-gated, above-threshold settlement. USB via @ledgerhq/hw-transport-node-hid; WebHID/Speculos via an injected context.ledgerTransport.

Docs-only change, following the existing third-party plugin entry format. Commit is DCO signed-off.
