[CLI-util] Replace Xdebug console logs with CLI output

[mho22]

Motivation for the change, related issues

Both @php-wasm/cli and @wp-playground/cli duplicate the same inline ANSI formatting helpers and use raw console.log calls for Xdebug output. This makes the output inconsistent across CLIs and harder to maintain.

This pull request extracts a shared CLIOutput base class into @php-wasm/cli-util and replaces all Xdebug-related console.log calls with it in both CLIs.

Implementation details

• New CLIOutput class in @php-wasm/cli-util : provides TTY-aware ANSI formatting and generic output methods. Uses a configurable writeStream and respects a verbosity setting.
• @php-wasm/cli: removed standalone formatting functions and /* eslint-disable no-console */. Imports CLIOutput from @php-wasm/cli-util directly. All Xdebug console.log calls replaced with cliOutput.print().
• @wp-playground/cli : the existing CLIOutput class now extends the base from @php-wasm/cli-util, removing its duplicated private formatting methods. Playground-specific methods remain. Standalone formatting functions in run-cli.ts removed. All Xdebug console.log calls replaced with cliOutput method calls.
• Tests added for the base CLIOutput class covering formatting, output methods, quiet mode suppression, and getter behavior.

Testing Instructions (or ideally a Blueprint)

CLI

🧪 packages/php-wasm/cli-util/src/test/cli-output.spec.ts

8 console.log remain in the packages/playground/cli/src/run-cli.ts. I am not sure I should replace them with cliOutput here.
