A big thank you to @Hocnonsense for this PR. This commit addresses multiple edge cases and improves the reliability and output of snakefmt, resolving several long-standing issues:

    Safer handling of multi-piece strings and f-strings, resulting in more robust formatting.
    More compact and stable formatting of inline parameters.
    Improved consistency of indentation and alignment for complex string and parameter scenarios.
    Enhanced parsing error messages for clearer diagnostics.
    Updated supported Python targets to 3.11–3.13 and adjusted the CI matrix accordingly.
    Switched configuration parsing to Python’s standard library TOML reader, reducing dependencies.
    CLI tests now assert stdout, and additional regression tests were added for complex parameter handling.
    The “one-line” format now gracefully falls back to normal style where appropriate.
    Delegated line merging and comment handling to Black for improved output.

Issues addressed:
Fixes #190, #208, #240, #242, and closes #255.
