Fix Knot Behavior, Interaction Safety, and Cleanup Logic

[evanbones]

• Added logic to automatically discard empty knots, so if a knot has no incoming or outgoing connections (e.g., when the other end of a chain is broken), it will now instantly disappear
• Knots now check for a valid attachment block and are discarded immediately if the supporting fence or block is removed
• Players can now punch knots to break them
• Using shears to break knots now reduces its durability
• Knots now enforce type checking, so you can't mix and match different catenary types on a single knot
• Fixed issue where collision entities would persist on servers
• Added additional check for chunk load safety (possibly fixes [Bug]: Vanishing Chains/ Rope #73?)
• Added config option to disable chain collision

I'm open to making any changes if you'd like, as some of these things could be considered major behaviour changes. Let me know!

Thank you for taking the time to work on it.
Will look at it when I have time.

Some of these changes are pretty opinionated, so feel free to just cherrypick any changes you'd like, but they're also implemented in a multiloader fork I made of the mod

[legoatoom]

Wow, you made a multiloader version‽ Why did you not make that a PR?

[evanbones]

It was pretty close to a full rewrite since the mappings had to be changes to mojamps and I made a lot of much more opinionated changes like increasing max chain distance to 128, but if you'd like I'd be happy to take down my fork and maintain a separate multiloader version? Or if you want to just cherry pick the multiloader logic from my fork? Up to you really
