Claude v0 of ARB INT/NUM

[frankmcsherry]

This is pointing Claude Code at columnar's arb.rs which has add/sub/mul for arbitrary precision integers. No idea what it looks like yet, and putting up to take a peek.

Thanks for opening this PR! Here are a few tips to help make the review process smooth for everyone.

PR title guidelines

• Use imperative mood: "Fix X" not "Fixed X" or "Fixes X"
• Be specific: "Fix panic in catalog sync when controller restarts" not "Fix bug" or "Update catalog code"
• Prefix with area if helpful: compute: , storage: , adapter: , sql:

Pre-merge checklist

• The PR title is descriptive and will make sense in the git log.
• This PR has adequate test coverage / QA involvement has been duly considered. (trigger-ci for additional test/nightly runs)
• If this PR includes major user-facing behavior changes, I have pinged the relevant PM to schedule a changelog post.
• This PR has an associated up-to-date design doc, is a design doc (template), or is sufficiently small to not require a design.
• If this PR evolves an existing $T ⇔ Proto$T mapping (possibly in a backwards-incompatible way), then it is tagged with a T-proto label.
• If this PR will require changes to cloud orchestration or tests, there is a companion cloud PR to account for those changes that is tagged with the release-blocker label (example).

	#[sqlfunc(sqlname = "sub_int")]
	fn sub_arb_int<'a>(a: &'a [u8], b: &'a [u8]) -> Vec<u8> {
	int_sub(a, b)
	}
	#[sqlfunc(sqlname = "mul_int")]
	fn mul_arb_int<'a>(a: &'a [u8], b: &'a [u8]) -> Vec<u8> {
	int_mul(a, b)
	}

It uses the function name as the default sqlname, so no need to set it manually.
