Run dotnet format to fix existing code to match .editorconfig

[LeeCampbell]

Summary

Run dotnet format across the entire solution to reformat existing code to match the .editorconfig conventions.

Details

This is a one-time bulk reformatting pass.
It should be done as a standalone commit/PR so that git blame impact is isolated to a single commit, making it easy to skip with git blame --ignore-rev.

Steps:

1. Run dotnet format on the solution
2. Review the changes to ensure nothing unexpected
3. Commit with a clear message (e.g. "chore: apply dotnet format to match .editorconfig")
4. Add the commit SHA to a .git-blame-ignore-revs file so git blame can skip it

Acceptance Criteria

• All code formatted to match .editorconfig rules
• .git-blame-ignore-revs file created with the formatting commit SHA
• Build and tests still pass
• No functional code changes — purely whitespace/style

Dependencies

• Depends on Add .editorconfig with project coding conventions #114 (.editorconfig) being merged first
