* refactor(contracts): derive the public tool catalog from one contract-group list
toolContracts.ts and toolFamilies.ts each imported and listed the same
contract groups. toolContracts.ts now owns one ordered group object;
TOOL_CONTRACTS is its flattened values in the same catalog order, and
toolFamilies.ts reads TOOL_CONTRACT_GROUPS from it instead of re-importing
every group. The static catalog-source lint rule learns the
Object.values(groups).flat() composition so positional-contract enforcement
still discovers every group without executing modules.
* fix(lint): reject computed tool catalog groups
