nirium-mcp 0.6.3

Added

• README: documents the 11 Treasury tools (get_treasury_info, get_treasury_vault, get_treasury_vaults, get_treasury_strategy_asset, deploy_treasury_vault, deposit_to_treasury_vault, withdraw_from_treasury_vault, set_treasury_rebalance_manager, build_treasury_rebalance, submit_treasury_tx, execute_treasury_rebalance), missing since they shipped. Text taken from each tool's own description in the code. Says which build an unsigned XDR, which signs with Nirium's own key (execute_treasury_rebalance, invite-only), and under what condition.

Fixed

• prepublishOnly: npm run build added, so a future publish can't skip the build the way 0.6.1 did.
• README: "Run from source" and the LICENSE link pointed to the old nirium-sdk repo.
• Removed long dashes from README.
