1-1: Submodule bump: manual verification required

• Automated diff script did not detect the lib/rain.interpreter pointer change; manually confirm the previous and new SHAs and verify compatibility with orderbook’s current integration.
• Update the PR description with a changelog summary (old→new SHAs) and note any breaking changes.
• Ensure CI/workflows fetch submodules recursively or add an explicit git submodule update --init --recursive step to prevent build failures.

🧹 Nitpick (assertive)

Pinning and release notes.

Submodules pin to a commit by design; for traceability, please note the upstream tag/release (if any) that contains 542e95d and link to its release notes in the PR body. If this pulls API changes, plan a version bump here accordingly.

🤖 Prompt for AI Agents

In lib/rain.interpreter around lines 1 to 1, the PR pins a submodule to commit
542e95d but does not document the upstream tag/release or link to release notes;
update the PR body to state which upstream tag or release contains commit
542e95d and add a link to that release's notes, and if the upstream changes
include API modifications, update the package/version metadata in the repo (bump
the version) and document that planned version bump in the PR description.
