Sweep: introduce imosid force option that overwrites files without checking if it has modified or invalid sections

[paperbenni]

Checklist

• src/app.rs ✅ Commit 489683d

• Add a new command-line argument for the force option in the `Command::new("apply")` subcommand. The argument should be a flag (i.e., it does not take a value), and it should be optional. • Modify the code that handles the "apply" subcommand to pass the value of the force option to the `DotFile::applyfile` function.

• src/files.rs ✅ Commit 0aca5be

• Modify the signature of the `DotFile::applyfile` function to take an additional boolean parameter that indicates whether the force option is enabled. • In the `DotFile::applyfile` function, add a condition at the beginning of the function that checks if the force option is enabled. If it is, skip the checks for modifications and invalid sections. • In the `DotFile::write_to_file` function, add a condition that checks if the force option is enabled. If it is, skip the checks for modifications and invalid sections.

Step 2: ⌨️ Coding

• src/app.rs ✅ Commit 489683d

• Add a new command-line argument for the force option in the `Command::new("apply")` subcommand. The argument should be a flag (i.e., it does not take a value), and it should be optional. • Modify the code that handles the "apply" subcommand to pass the value of the force option to the `DotFile::applyfile` function.

• src/files.rs ✅ Commit 0aca5be

• Modify the signature of the `DotFile::applyfile` function to take an additional boolean parameter that indicates whether the force option is enabled. • In the `DotFile::applyfile` function, add a condition at the beginning of the function that checks if the force option is enabled. If it is, skip the checks for modifications and invalid sections. • In the `DotFile::write_to_file` function, add a condition that checks if the force option is enabled. If it is, skip the checks for modifications and invalid sections.

Step 3: 🔁 Code Review

I have finished reviewing the code for completeness. I did not find errors for sweep/force-option.
