docs(skills): verify current date for relative dates

[godququ5-code]

Summary

Add shared skill guidance so agents verify the current date/year before handling relative date requests. This prevents stale defaults such as assuming 2025 from examples, history, or model memory.

Changes

• Add a 时间与年份 section to lark-shared with explicit current-date verification guidance.
• Tell agents to use the runtime/system date, or run date when no reliable current date is available.

Test Plan

• Unit tests pass (not run; docs/skill-only change)
• Manual local verification confirms the lark-cli <domain> <command> flow works as expected (not applicable; no CLI behavior changed)

Validation run:

• node scripts/skill-format-check/index.js
• git diff --check

Related Issues

• Fixes The agent defaults to taking 2025 as the current year #1752

Summary by CodeRabbit

• Documentation
  • 新增“时间与年份”说明，明确在处理“今天、明天、本周、今年、当前年份”等相对日期时，应以运行环境或系统消息中的当前日期为准。
  • 当缺少可靠当前日期时，需先获取本机日期，避免从示例、历史对话或旧资料推断年份。
  • 明确不再默认使用 2025 作为当前年份。
