feat: add code toolset (#87)

* feat: add code generation toolset and update enabled resources

- Introduced `getCodeGenerationInstructions` tool to provide step-by-step guidance for generating API client code from Postman collections.
- Added `getCollectionMap` tool to retrieve a recursive index of all folders and requests in a Postman collection.
- Updated `enabledResources` to include new tools and modified the `excludedFromGeneration` list.
- Enhanced the `run` function to support a new `--code` argument for selecting code generation tools.
- Adjusted `ServerContext` to accommodate the new 'code' server type.

* feat: add code toolset bundling flows

* feat: add searchPostmanElements tool

* Various README updates for code toolset

* Tweaks to code manifest description and long description
