Bump rain.metadata submodule for stale OrderBuilderStateV1 doc comment

[findolor]

Dependent PRs

• Rename DotrainGuiStateV1 to OrderBuilderStateV1 rain.metadata#93

Motivation

rain.metadata includes a fix for a stale OrderBuilderStateV1 doc comment. This submodule bump pulls that fix into rainlang.

Prior art: #436

Solution

• bump lib/rain.metadata from 182db238b53895b8490ac13208b2580eab817f36 to 952b49c9181d95fd6a1bc86e0200297f35982b5a
• no code changes outside the submodule pointer

Checks

By submitting this for review, I'm confirming I've done the following:

• made this PR as small as possible
• unit-tested any new functionality
• linked any relevant issues or PRs
• included screenshots (if this involves a front-end change)

Validation run locally:

• nix develop -c rainix-sol-prelude
• nix develop -c rainix-rs-prelude
• nix develop -c rainlang-prelude
• nix develop -c rainix-rs-test
• nix develop -c rainix-rs-artifacts
• nix develop -c rainix-rs-static
• nix develop -c rainix-sol-static
• nix develop -c forge build
• nix develop -c test-wasm-build
• nix develop -c forge script ./script/BuildPointers.sol
• nix develop -c forge fmt

nix develop -c rainix-sol-test still requires CI RPC environment variables locally (CI_FORK_ETH_RPC_URL, CI_DEPLOY_*_RPC_URL, ETH_RPC_URL).

🐰 A whisker twitch, a nibble here,
The metadata hops to a state more dear,
One commit hash swapped for its twin,
Progress wrapped up, tucked neatly in! 🥕

Submodule pointer has mismatched commits and missing required interface file—will cause build failure.

The diff shows submodule commit 0cfba664c5a381662ed4436979ad47e12e76c2a8, but:

• PR objectives state the target commit should be 952b49c9181d95fd6a1bc86e0200297f35982b5a
• The actual submodule HEAD is 8b92e198b323d908f8bfb965f3f0371fd83a991d

More critically, the parent repo imports IDescribedByMetaV1 from rain.metadata/interface/IDescribedByMetaV1.sol, but this file does not exist in the current submodule state. This will break compilation.

Resolve the commit mismatch and ensure the intended submodule commit contains all required interface files.
