fix(skill): use existing 'review-work' skill name in tool examples (fixes #3285)

[MoerAI]

Summary

• Replace non-existent 'code-review' example with actual 'review-work' skill name in tool schema

Problem

The skill tool's description and argument schema reference 'code-review' as an example skill name, but this skill does not exist. Users who follow the example get an error. The actual built-in review skill is named 'review-work'.

Fix

Updated both references from 'code-review' to 'review-work'.

Changes

File	Change
src/tools/skill/constants.ts	Update example in TOOL_DESCRIPTION_PREFIX
src/tools/skill/tools.ts	Update example in argument schema description

Fixes #3285
