Bug

Dividing or taking the modulo of two integers by zero crashes dasel:

$ echo '{}' | dasel -i json '1 / 0'
panic: runtime error: integer divide by zero

goroutine 1 [running]:
github.com/tomwright/dasel/v3/model.(*Value).Divide(...)
	model/value_math.go:177

5 % 0 panics the same way. The same happens through the Go API (dasel.Select, Query), so a library caller evaluating a user-supplied selector gets a panic rather than an error.

Cause

Value.Divide and Value.Modulo apply Go's / and % directly in the int/int branch, and Go panics on integer division by zero. The float branches don't panic (they produce +Inf/NaN), so this only affects the int/int case.

Fix

Check for a zero divisor in the int/int branches and return a new model.ErrDivisionByZero. After the change:

$ echo '{}' | dasel -i json '1 / 0'
dasel: error: error executing selector: execution error when processing ast.BinaryExpr: integer division by zero

Test

TestValue_IntegerDivisionByZero in model/value_math_test.go covers Divide and Modulo. It panics before the change and passes after. go test ./... and golangci-lint run ./model/... pass.

No documentation changes needed.
