Find and Replace Functionality

[tom-ludwig]

This PR adds simple search and replace functions. The first one, searchAndReplace, can replace all occurrences of a search term across the workspace. The second, replaceRange, lets you replace text in a specific range within a file. Depending on the range, it's useful for replacing a single term in a file or even within a function.

Additional Improvements

• Implement visual feedback in the Find Navigator to display current states such as 'Searching...', 'Replacing...', 'Found...', and 'Failed,' in compliance with Apple's human interface guidelines: Apple suggests using visual feedback to acknowledge user input and provide a clear indication that an action is taking place.
• Remove duplicate 'Match Whole Word' option from the search text field
• Fix bug preventing proper functionality of search options such as 'Match Word,' 'Starting with,' and 'Ending with'.

I might use checkmark.circle.fill instead of checkmark.diamond.fill. I believe diamond symbols in Xcode usually indicates tests. We should also replace searching... with a spinner indicator.

What is the difference between No Results, and An Error Occurred? The subtitle is very similar. I might also look into which symbols are being used here as well.

I've changed the symbol and added a ProgressView().

For folks who missed the meetup: I wanted to highlight the difference between an unsuccessful search and a unsuccessful find-and-replace.

For reviewers: The existing search and Find And Replace algorithm lacks real-time progress visibility for users, meaning it doesn't promptly display the found files or terms that have been replaced. I already have plans for an upcoming pull request where the results will be delivered incrementally (the result will be returned in chunks).
