Make review CLI commands honor reject and next actions

[getOffIt]

Summary

The TypeScript review command path exposes review-reject and review-next, but only accept has real behavior.

Problem

executeReview() in voice-tool/src/services/CommandModeHandler.ts plays audio and handles accept, but it does not implement the reject/next decision path. Those commands currently succeed without doing what their names imply.

Impact

Automation and operator workflows can report success while leaving review state unchanged.

Relevant code

• voice-tool/src/services/CommandModeHandler.ts:113-133
• voice-tool/src/cli/CLIInterface.ts:252-260

Expected behavior

review-reject and review-next should either perform the documented action or fail explicitly.

Suggested direction

• Implement the reject/next decision flow in the TypeScript command handler.
• If that functionality is intentionally unsupported in this path, remove the commands or return a clear error instead of success.
• Add command-level tests for accept, reject, and next behavior.
