Bump version to 0.14.0, update `CHANGELOG.md`

[MaxDesiatov]

New release is required to resolve https://github.com/TokamakUI/Tokamak/pull/475.

I've also cleaned up formatting in .ts file and clarified version incompatibility error message.

BTW I think this new release is not required for the Tokamak PR. Is there any essential change?

[MaxDesiatov]

https://github.com/swiftwasm/carton/pull/310 relies on reactor model, which was updated in https://github.com/swiftwasm/JavaScriptKit/pull/180, wasn't it? And then .jsValue() -> .jsValue change was breaking, I'd like to update Tokamak codebase for it sooner rather than later.

Either way, I've already tagged it, sorry if that was premature 😅

180 is only for test harnesses, so no change in the js runtime. Yeah, it's fine to release breaking changes soon.
