Chat attachment file picker search path is broken when using Workspace

[DBNDeveloper]

When trying to add files to Chat via the attachment picker, files that should be available aren't and files that should not be available are. It seems that when in an Xcode workspace, the Chat file picker simply scans directories that are adjacent to the workspace and makes all files available even if the adjacent directories and subdirectories are not in the workspace.

Versions

• Copilot for Xcode: 0.31.0
• Xcode: 16
• macOS: 5.2

Steps to reproduce
Bug 1. Too Greedy

1. Create a Demo directory in file system
2. Create a Projects directory inside Demo Demo/Projects
3. Create ProjectA in Projects Demo/Projects/ProjectA
4. Create ProjectB in Projects Demo/Projects/ProjectB
5. Save ProjectA as a Workspace in the Projects directory Demo/Projects/ProjectA.xcworkspace
6. Open ProjectA.xcworkspace
7. Open Chat Window Attach Context Picker

Results: ProjectB files are available to attach to Chat, they shouldn't be.

Bug 2. Too limited

1. Create a Packages directory in demo Demo/Packages
2. Create a PackageA in the Packages Demo/Packages/PackageA
3. Edit the package as a local dependecy within the workspace
4. Open Chat Window Attach Context Picker

Results: All project files are available, but only the focused package file is available. We cant add other files from the package.

The issue seems be be in ContextUtils.getFilesInActiveWorkspace() which makes no use of the workspaceURL :

    public static func getFilesInActiveWorkspace() -> [FileReference] {
        guard let workspaceURL = XcodeInspector.shared.realtimeActiveWorkspaceURL,
              let projectURL = XcodeInspector.shared.realtimeActiveProjectURL else {
            return []
        }

        do {
            let fileManager = FileManager.default
            let enumerator = fileManager.enumerator(
                at: projectURL,
                includingPropertiesForKeys: [.isRegularFileKey, .isDirectoryKey],
                options: [.skipsHiddenFiles]
            )

            var files: [FileReference] = []
            while let fileURL = enumerator?.nextObject() as? URL {
                // Skip items matching the specified pattern
                if matchesPatterns(fileURL, patterns: skipPatterns) {
                    enumerator?.skipDescendants()
                    continue
                }

                let resourceValues = try fileURL.resourceValues(forKeys: [.isRegularFileKey, .isDirectoryKey])
                // Handle directories if needed
                if resourceValues.isDirectory == true {
                    continue
                }

                guard resourceValues.isRegularFile == true else { continue }
                if supportedFileExtensions.contains(fileURL.pathExtension.lowercased()) == false {
                    continue
                }

                let relativePath = fileURL.path.replacingOccurrences(of: projectURL.path, with: "")
                let fileName = fileURL.lastPathComponent

                let file = FileReference(url: fileURL,
                                           relativePath: relativePath,
                                           fileName: fileName)
                files.append(file)
            }

            return files
        } catch {
            Logger.client.error("Failed to get files in workspace: \(error)")
            return []
        }
    }
