feat: run string reflowing in IntelliJ plugin

[st1020]

Run string reflowing in the IntelliJ plugin, making the behavior of the IntelliJ plugin consistent with the default behavior when using the jar.

An alternative solution would be to provide an option like --skip-reflowing-long-strings in the IntelliJ plugin, but I believe their default behavior should remain consistent when no options are explicitly enabled.

Fixed #566
