[panditdhamdhere]

Summary

Fix two typos in documentation and configuration files.

Changes

1. README.md (line 80)

   • incidating → indicating
   • Context: "A glob pattern indicating which contracts are in scope."

2. rustfmt.toml (line 1)

   • unfortunetely → unfortunately
   • Context: "cargo fmt does not support 'out of the box' formatting unfortunately"

Impact

Minor documentation/typo fixes. No behavior changes.
