Remove unused extractMetadataFromRemoteFile function

[Copilot]

The lint-go workflow is failing on PR #16423 due to an unused function extractMetadataFromRemoteFile in pkg/cli/list_workflows_command.go.

Root Cause

The function was intended to fetch metadata (engine ID, labels, on field) from remote workflow files, but the implementation deliberately returns "N/A" for all remote metadata to avoid slow API/git calls:

// For remote repos, skip fetching individual file metadata to avoid slowness
if isRemote {
    workflows = append(workflows, WorkflowListItem{
        Workflow: name,
        EngineID: "N/A",
        Compiled: "N/A",
        Labels:   nil,
    })
}

This renders extractMetadataFromRemoteFile dead code.

Changes

• Removed 67 lines of unused helper function from pkg/cli/list_workflows_command.go
• No functional impact (function was never called)
• Resolves golangci-lint unused checker failure
