enable jsr build

Thanks to @sigmaSd for getting this off the ground!

I vendored the last version of deno-snapshot_preview1 available (v0.206.0),
added very basic type definitions for `Deno`, and sprinkled in some `as <type>`
annotations into the codebase.

I've also merged the "jsr publish" into the release workflow.
