Refactor core to align runtime and utility helpers

[GuTaoZi]

This pull request primarily focuses on improving code readability and consistency by reformatting and modernizing the code style across several files. The changes include updating brace placement, converting multi-line function definitions to single-line where appropriate, and standardizing the use of else statements. Additionally, some minor improvements were made to logging output and command formatting.

Code style and formatting improvements:

• Converted multi-line function definitions and constructors in src/bots/shinxbot.cpp, src/bots/shinxbot.hpp, and src/bots/shinxbot_meta.cpp to single-line where possible, improving code compactness and readability. [1] [2] [3] [4]
• Standardized the use of else by placing it on the same line as the closing brace of the previous if block, and updated related conditional formatting throughout src/bots/shinxbot_meta.cpp. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Logging and output improvements:

• Improved logging output by ensuring formatted messages use explicit format strings in fmt::print calls in shinxbot::setlog.

Command and string formatting enhancements:

• Broke up long command and error message strings for better readability and maintainability, especially in command construction and error reporting in src/bots/shinxbot_meta.cpp. [1] [2] [3] [4] [5] [6]

Configuration updates:

• Changed the brace style in .clang-format from Stroustrup to Attach to enforce the new code style project-wide.

Include order:

• Reordered includes in src/bots/shinxbot_meta.cpp to maintain a consistent and logical order.
