修了一大堆问题

[WSXYT]

This pull request focuses on improving the application's restart mechanism and the update checking experience, along with several bug fixes and minor enhancements. The main changes include a robust solution for the restart feature to prevent deadlocks and unwanted command line windows, more accurate update check time handling, and improved user feedback during update checks. Additionally, several bug fixes and language improvements are included.

Application Restart Mechanism Improvements:

• Refactored the restart logic to use an exit code (EXIT_CODE_RESTART) for signaling a restart, moving the actual process relaunch logic to main.py. This approach ensures only a single instance is running and prevents command line windows from appearing on restart, especially on Windows. [1]], [2]], [3]], [4]], [5]], [6]])
• Added cross-platform process spawning logic in main.py that handles relaunching the application cleanly after receiving the restart exit code, with special handling to avoid console windows on Windows. [1]], [2]])

Update Checking and UI Enhancements:

• Improved update check workflow: now uses a Qt signal (update_check_finished) to ensure UI updates and last check time are handled in the main thread, and accurately reflects the last successful check. [1]], [2]], [3]], [4]], [5]], [6]], [7]])
• Enhanced last update check time display: shows "Never checked" if the update check has never been performed, with new language entries for both Chinese and English. [1]], [2]], [3]])

Bug Fixes and Minor Improvements:

• Fixed issues with the update check time not updating after a successful check, and display errors when never checked. ([CHANGELOG/v2.2.0/CHANGELOG.mdL50-R56])
• Fixed the settings linkage page issue where reopening the page would result in a blank display. ([app/view/settings/settings.pyR646-R649])
• Corrected Sentry initialization logic to only enable it in non-development builds and enabled log capturing. [1]], [2]])

Changelog Updates:

• Updated the changelog to reflect the above bug fixes and improvements, including more detailed descriptions of the restart and update check fixes. ([CHANGELOG/v2.2.0/CHANGELOG.mdL50-R56])

The restart logic filters out command-line arguments starting with "--" on line 211, but then unconditionally includes filtered_args[1:] implicitly. The first element of sys.argv (sys.argv[0]) is the script/executable name, and should be excluded from filtered_args. Currently, if sys.argv[0] doesn't start with "--", it will be included in filtered_args and passed as an argument to the new process. The filter should exclude sys.argv[0] by using filtered_args = [arg for arg in sys.argv[1:] if not arg.startswith("--")].

Suggested change

	# 过滤掉 --url 等参数
	filtered_args = [arg for arg in sys.argv if not arg.startswith("--")]
	# 过滤掉 --url 等参数，并且跳过 sys.argv[0]（可执行文件路径）
	filtered_args = [arg for arg in sys.argv[1:] if not arg.startswith("--")]

The comment is incorrect - it states "仅在开发环境（版本号不包含 0.0.0）下初始化 Sentry" (Only initialize Sentry in development environment where version doesn't contain 0.0.0), but the condition if "0.0.0" not in VERSION: actually initializes Sentry in non-development builds (when version doesn't contain "0.0.0"). The comment should say "仅在非开发环境" (Only in non-development environment) or the logic should be inverted to match the comment.

Suggested change

	# 仅在开发环境（版本号不包含 0.0.0）下初始化 Sentry
	# 仅在非开发环境（版本号不包含 0.0.0）下初始化 Sentry
