fix(drizzle-valibot): handle compound dataType strings for UUID and other columns

[MaxwellCalkin]

Summary

Fixes #5338

When using drizzle-orm@1.0.0-beta.* with drizzle-valibot@0.4.2, createSelectSchema() produces v.any() (which becomes {} in OpenAPI) for UUID columns instead of the expected v.pipe(v.string(), v.uuid()).

Root cause

drizzle-orm beta changed column dataType from simple strings to compound strings:

Column	Stable dataType	Beta dataType
uuid()	"string"	"string uuid"
integer()	"number"	"number int32"
json()	"json"	"object json"
bytea()	"buffer"	"object buffer"

columnToSchema() in drizzle-valibot uses exact equality checks like column.dataType === 'string', which fails for "string uuid". The UUID column falls through all checks and lands on the v.any() fallback.

Fix

Extract the base type from the first word of column.dataType (e.g. "string uuid".split(' ')[0] = "string") before matching. This way both "string" (stable) and "string uuid" (beta) route to stringColumnToSchema(), which already handles PgUUID correctly via isColumnType().

Also added handling for the new "object <constraint>" compound types (buffer, date, json) that the beta uses.

Note

The same bug exists in drizzle-zod, drizzle-typebox, and drizzle-arktype — they all use the same column.dataType === '...' pattern. This PR only fixes drizzle-valibot as reported in the issue, but the same fix should be applied to the other packages.

Test plan

• Existing tests continue to pass (they use stable dataType strings)
• Verified that "string uuid".split(' ')[0] correctly extracts "string", routing UUID columns to stringColumnToSchema() which returns v.pipe(v.string(), v.uuid())
• The fix is backward-compatible: for stable dataType values like "string", "string".split(' ')[0] = "string" — same result as before
