feat(core): enhance spinner handling and add spinner to inferred conversion

[meeroslav]

This PR creates a global spinner handler and adds the runtime information to the convert-to-inferred migration process.

The global spinner ensures a single instance of the ora spinner. The ora cannot run several instances in parallel, so running multiple instances causes flickering due to message deletion.

The covert-to-inferred plugin migration will now show the loading spinner and progress indicator specifying how many projects have been converted.

Additional changes:

• DelayedSpinner will not show if there is another (parent) spinner already running.

The stop() method should check if this.#ora exists before calling stop() on it. Currently, if stop() is called before start(), this.#ora will be undefined and cause a runtime error. Consider adding a null check:

stop() {
  if (this.#ora) {
    this.#ora.stop();
  }
}

This pattern is already used correctly in the updateText() method below.

Suggested change

	stop() {
	this.#ora.stop();
	}
	stop() {
	if (this.#ora) {
	this.#ora.stop();
	}
	}

Nx Cloud has identified a possible root cause for your failed CI:

The failure analysis reveals that the nx-dev:build-base task failed because Next.js cannot find the directory public/documentation/blog during static page generation for the /blog/[slug] route.

Classification rationale for 'environment_state':

1. No correlation with PR changes: The PR modifies spinner handling utilities, test setup code, documentation markdown files, and ESLint generator configuration. None of these changes involve:

   • Deleting or moving the public/documentation/blog directory
   • Modifying blog-related functionality
   • Changing Next.js static generation configuration
   • Altering file system operations related to the blog

2. File system error unrelated to code logic: The error is "ENOENT: no such file or directory" - a fundamental file system issue indicating a missing directory that should exist in the repository structure. This is not a code logic error that could be introduced by the PR's changes.

3. Pre-existing repository issue: The missing directory represents a pre-existing problem in the repository environment. The similar task failure outputs from the master branch were empty, suggesting this may be an intermittent or environment-specific issue rather than something introduced by this PR.

4. Direct inspection of changes: Reviewing the complete diff shows:

   • Creation of packages/nx/src/utils/spinner.ts with a new SpinnerManager class
   • Updates to various files to use globalSpinner instead of local ora instances
   • Simplification of newProject() calls in e2e tests
   • Documentation updates to markdown files (adding {% frame="none" %} attributes and removing manual dependency management sections)
   • ESLint generator changes to remove deprecated TypeScript ESLint packages

None of these modifications would cause or relate to a missing blog directory in the nx-dev public folder.

The failure is definitively classified as 'environment_state' because it represents a missing file system resource that is completely unrelated to the PR's scope of work around spinner handling and test improvements.

A code change would likely not resolve this issue, so no action was taken.
