fix(cloud-mcp): add CloudflareResource + VercelResource enums to Zig FFI (standards#150) (#125)

Class C ABI gap. `CloudflareResource` (7 variants) + `VercelResource` (5
variants) were Idris2-only.

Multi-cap Idris2 names follow the current iseriser converter output
(e.g. `CfKVNamespace → cf_kvnamespace`); when iseriser#18 (multi-cap
normaliser) lands these may be canonicalised. Noted inline.

`iseriser abi-verify` → exit 0 (4 enums, 6 transitions); `zig build
test` → 28/28 green.

Closes hyperpolymath/standards#150
