docs(README.md): remove shell script formatting section

Remove the section on shell script formatting from the README.md
as it is no longer relevant or necessary for the current state of
the project. The project may have evolved to a point where these
instructions are outdated or the formatting is now handled by
other means, such as a different tool or process. This helps
streamline the documentation and reduce potential confusion for
contributors.

-## Shell Script Formatting
-
-This project uses bash scripts with bash-specific features (arrays, `[[` builtin, etc.). Script formatting is configured via `.editorconfig` and can be applied using shfmt:
-
-```bash
-# Format all shell scripts (uses .editorconfig settings)
-shfmt -w scripts/*.sh src/backend/*/scripts/*.sh
-
-# Check formatting without modifying files
-shfmt -d scripts/*.sh src/backend/*/scripts/*.sh
-```
-
-The `.editorconfig` file automatically configures shfmt with:
-- 2-space indentation
-- Bash shell variant
-- Case statement indentation
-- Space after redirects
-- Binary operators on new lines
-
