Summary: Re-implement analyze and classify command paths in yargs with parity for automation-oriented JSON contracts.

User Story

As a pipeline user, I can run analysis/classification jobs with stable argument validation and machine-readable outputs that do not break existing scripts.

Expected UX Change

• User experience: consistent command ergonomics and clearer validation messages.
• Player experience: downstream sound selection/labeling outcomes remain equivalent for identical inputs.

Acceptance Criteria

• analyze and classify execute through yargs handlers, including currently supported modes.
• --json schema/shape remains compatible for existing consumers.
• Batch and single-input scenarios are covered by integration tests.
• Help output and error semantics are parity-tested for key invalid-input cases.

Minimal Implementation

• Add yargs modules/builders for analyze and classify.
• Reuse current domain services and output adapters to preserve behavior.
• Add contract tests that assert JSON shape stability.
• Remove command-specific legacy dispatch for these commands once parity is green.
