Replace elegant-spinner with ora (default settings)

[Copilot]

Replaces the elegant-spinner dependency with ora@9.3.0 (latest) using its default settings.

Changes

• package.json: Swapped elegant-spinner: 2.0.0 for ora: 9.3.0 in dependencies
• tsconfig.json: Changed "module" to "node16" and added "moduleResolution": "node16" so TypeScript emits a true dynamic import() expression (rather than compiling it to require()), enabling the CJS extension host to load the ESM-only ora package
• src/extension.ts: Replaced the static require-style import with a dynamic import('ora') call in the constructor; the resolved Ora instance's frame() method is stored as a spinnerFrame function reference and used in place of the previous statusBarSpinner.frame() calls

Since ora v5+, the package is ESM-only. The frame() method returns the next spinner frame string and remains a drop-in replacement for the previous elegant-spinner behaviour.

Updated to ora 9.3.0 in commit 6749877. Since v5+ is ESM-only, I switched tsconfig.json to "module": "node16" so TypeScript emits a true dynamic import() (rather than compiling it to require()), and replaced the static import with a dynamic import('ora') in the constructor that stores a spinnerFrame function reference used in the status bar interval.

Closing as wontfix.
