Mod API levels: server mods' players functions are level 1; the registry's lockfile

Main gained players.online, tell and broadcast (#1833) after 0.2.69, so
they take level 1 with render.set-minimap. horizon-mod-registry's own
Cargo.lock picks up wasmparser.

 A new WIT function doesn't break older mods, but a mod that calls it can't run on a Horizon from before it. So every
