Support city name as CLI parameter and add WeatherSkill module

[Copilot]

--city previously accepted only a raw numeric city code; there was no importable interface for weather queries. This PR changes --city to accept a human-readable city name and adds WeatherSkill.py as a reusable skill module.

GetWeather.py

• --city now takes a city name (e.g. 北京) and resolves it to a code via get_city_code() internally
• main_weather_process() gains city_name=None; when set, skips IP-based auto-detection entirely
• --debug mode similarly resolves city name → code with an explicit error on lookup failure

WeatherSkill.py (new)

• query_weather(city_name: str) -> str — named-city lookup, returns weather text, no sys.exit side-effects
• query_weather_auto() -> str — IP-based auto-detection variant
• Usable as an importable module or standalone CLI

# GetWeather.py — direct city name
python GetWeather.py --city 北京

# WeatherSkill.py — as a skill/module
from WeatherSkill import query_weather
print(query_weather("上海"))

# or as CLI
python WeatherSkill.py --city 广州

Misc

• Added .gitignore covering __pycache__/, *.pyc, response.html, debug_results.json

Original prompt

查看仓库代码，修改为支持参数传递城市名称，输出天气结果，然后编写一个查询天气的Skill，使用这个脚本

Pull request overview

This PR changes the --city CLI parameter from accepting a raw numeric city code to accepting a human-readable city name (e.g., 北京), and introduces a new WeatherSkill.py module that wraps the weather querying logic into a clean, importable API.

Changes:

• GetWeather.py: --city now accepts a city name resolved via get_city_code(), and main_weather_process() gains a city_name parameter to skip IP-based auto-detection
• WeatherSkill.py (new): Provides query_weather() and query_weather_auto() functions as a reusable module with error handling via return values instead of sys.exit()
• .gitignore (new): Ignores __pycache__/, *.pyc, *.pyo, response.html, and debug_results.json
