Fix: AI-generated file path issues with -i

[RareMojo]

Remove workspace\ from the file_list.txt context to prevent nesting another workspace folder.

Could do this a dozen ways.
Core issue: GPT would state filenames as workspace\... causing new file creation and no overwrites.

Can you make a solution that does this, but:

• works on all operating systems
• only targets directories that are called exactly workspace (the current one can distort cases when workspace is a substring in an actual directory)
• Only removes the first occurrence of a folder called workspace in the path

I may be missing something :)

I imagine this is obsolete, now that the concept of workspace has been removed. Happy to open again in case I'm wrong
