Make effect-schema bufferSchema browser-safe

[marbemac]

The new drizzle-orm/effect-schema package (added in beta.15) has the same browser compatibility issue that was previously fixed for drizzle-arktype in #4424.

In effect-schema/column.ts:

export const bufferSchema = S.instanceOf(Buffer) satisfies Schema<Buffer>;

S.instanceOf(Buffer) evaluates Buffer eagerly at module load time. In browser environments Buffer doesn't exist, so importing drizzle-orm/effect-schema crashes immediately — even if none of your tables use buffer columns.

Same class of issue as #4383. The other validator packages (zod, valibot) already avoid this because zod.custom() / v.custom() wrap the instanceof check in a callback. The arktype fix in #4424 did the same thing.

Fix

// before — eagerly evaluates Buffer at import time
export const bufferSchema = S.instanceOf(Buffer) satisfies Schema<Buffer>;

// after — Buffer is only referenced at validation time
export const bufferSchema: Schema<Buffer> = S.declare(
	(input: unknown): input is Buffer => input instanceof Buffer,
);

Uses S.declare with a type guard so Buffer is only referenced when the schema is actually used for validation, not at module load. Same runtime behavior, just deferred.
