Replace olekukonko/tablewriter with text/tabwriter

[adrianreber]

After some anonymous third party review, I completed changed the approach to this PR. Instead of using the external dependency tablewriter this now uses text/tabwriter. This reduces included code.

Drop external tablewriter dependency in favor of Go's built-in text/tabwriter package to reduce dependencies and simplify maintenance.

Changes:

• Replace tablewriter.NewWriter() with tabwriter.NewWriter() in all table display functions
• Update table formatting logic to use tab-separated output with headers and separator lines
• Remove olekukonko/tablewriter and related dependencies from go.mod
• Update test expectations to match new table output format
• Fix test line number references after table format changes

All tests pass with the new implementation.

@rst0git @snprajwal This update was created with Claude. The main reason to create was that dependabot now combines all changes and the tablewriter change breaks API. That is why I wanted to do it in a separate PR.

The new tablewriter comes with new features and new dependencies which increase the binary size. Not sure if this is too much. If I am able to correctly read the number it is 700KB larger than before.

@adrianreber AI models sometimes generate code that is incorrect. It compiles and runs but does not do what we want.

Let me also update README.md.

Dropping tablewriter decreases binary size by 400K

@adrianreber Would it be possible to apply the following changes to your patch?

rst0git@782df66

This approach is similar to the one used in:

• https://github.com/kubernetes/cli-runtime/blob/master/pkg/printers/tabwriter.go
• https://github.com/kubernetes/cli-runtime/blob/4ef9d6338/pkg/printers/tableprinter.go#L189

I told claude to update the PR with the changes @rst0git suggested.

It seems like Claude doesn't know that it also needs to update the README file.
