This commit applies the new canonical formatting style using `clang-format` with custom settings (notably 4-space indentation), as part of our shift toward automated formatting normalization. ⚠️ No functional changes are included — only whitespace and layout modifications as produced by `clang-format`. This change is part of the formatting modernization strategy discussed in: https://github.com/rsyslog/rsyslog/issues/5747 Key context: - Formatting is now treated as a disposable view, normalized via tooling. - The `.clang-format` file defines the canonical style. - A fixup script (`devtools/format-code.sh`) handles remaining edge cases. - Formatting commits are added to `.git-blame-ignore-revs` to reduce noise. - Developers remain free to format code however they prefer locally.
