feat: all posts link end with /

[ccbikai]

Both the canonical and RSS article URLs end with "/", for consistency with the standard, it is best to use "/" at the end of the article URL.

Otherwise, there will be an additional 308 redirect.

Yes.
You're right.
Besides your updates, I found that other links also need to have trailing slash in order to prevent unnecessary redirects.
Thanks for pointing this out.
