Pull request overview

This PR renames the "Claude Skills" feature to "Agent Skills" to make it more vendor-agnostic and generalized. The renaming affects interfaces, method names, configuration keys, file paths, test cases, and user-facing messages throughout the chat/prompts subsystem.

Key Changes

• Renamed IClaudeSkill interface to IAgentSkill and findClaudeSkills() method to findAgentSkills() across service interfaces and implementations
• Updated configuration key from USE_CLAUDE_SKILLS to USE_AGENT_SKILLS and changed the file system path from .claude/skills to .agent/skills
• Updated all tests, comments, documentation, and localized strings to use "Agent" terminology instead of "Claude"
