Add a CLI helper script wrapping the README's stellar contract invoke examples

[james2177]

Description

README's usage examples (README.md:38-68) require manually substituting <CONTRACT_ID>/<SECRET_KEY>/addresses into stellar CLI invocations each time -- a thin wrapper script would reduce this boilerplate for local testing.

Requirements and context

• Use the exact commands/parameters already documented in README as the basis

Suggested execution

1. Fork the repo and create a branch

   git checkout -b tooling/cli-invoke-wrapper
   

2. Add a scripts/invoke.sh (or similar) reading common parameters from environment variables or a config file
3. Update README to mention the shortcut alongside the raw commands

Example commit message
