Rust-Plugins now releases a ZoneManager helper, RunicGatewayZones.cs, beside
the bridge (docs/modules/rust/PLAN_FIXES.md D181, D182), installed by default.
The egg copied only RunicGateway.cs out of the tarball.

It now takes every .cs the plugin manifest lists in `files`, checks each
against its own sha256 before anything is placed (the bridge's own checksum
was never checked by the egg before), and refuses a name that is not a plain
<Name>.cs. A release older than helpers lists only the bridge and installs
exactly what it did before. Exercised in an Alpine shell against both, a
tampered helper, a missing one, `../evil.cs` and `evil.dll`.
