fix(ts-interface-generator): pass process.argv to yargs so CLI flags work

[akudev]

The yargs v18 migration (bf53c43) rewrote the CLI from the singleton
pattern (yargs.option({...}).argv) to the factory pattern
(yargs().option({...}).argv). The factory creates a detached instance
that never reads process.argv, so --jsdoc, --watch, --config, and
--loglevel were all silently ignored — every run used defaults.

Fix: pass hideBin(process.argv) explicitly per the yargs v18 API.

Closes #542

Pull request overview

This PR addresses @ui5/ts-interface-generator CLI flag parsing so --jsdoc minimal/none is correctly applied when invoked from the command line (root cause of issue #542), and adds regression tests around JSDoc preference behaviors.

Changes:

• Pass hideBin(process.argv) into yargs(...) so CLI flags are actually parsed.
• Add Jest tests validating JSDoc output differences for verbose, minimal, and none modes.
• Add tests demonstrating the yargs factory behavior that led to the regression.
