fix(devins-lang): improve file content extraction

#100

- Improve file content extraction to handle line ranges more accurately and efficiently.

The changes in `FileInsCommand.kt` allow for more precise extraction of file content based on line ranges, enhancing the accuracy and efficiency of the process. Additionally, in `DevInsCompiler.kt`, a new case for handling comments has been added to ignore comments during processing. Lastly, in `DevInsFlowProcessor.kt`, the usage of `runReadAction` has been added to ensure safe access to the PSI file.
