fix: 移除未使用的临时目录变量

[Copilot]

Removed 5 unused local variable assignments flagged by ruff check that were introduced during the path refactoring to AstrbotPaths.

Changes

• astrbot/core/message/components.py: Removed 3 unused temp_dir assignments and 1 unused download_dir assignment in Record, Video, and Image classes
• astrbot/core/platform/sources/wechatpadpro/wechatpadpro_adapter.py: Removed unused temp_dir assignment in voice message handling
• packages/python_interpreter/main.py: Removed unused temp_dir assignment in file upload handling

All affected code paths construct the full file path directly using AstrbotPaths.astrbot_root / "temp" / filename, making the intermediate directory string conversion redundant.

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• api.soulter.top
  • Triggering command: /home/REDACTED/work/AstrBot/AstrBot/.venv/bin/python3 main.py (dns block)
• astrbot-registry.soulter.top
  • Triggering command: /home/REDACTED/work/AstrBot/AstrBot/.venv/bin/python3 main.py (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
