Utilities for working with UUIDs.

# `valid?`

Checks if a string is a valid UUID.

Uses `Ecto.UUID.cast/1` for robust validation that handles
all UUID formats (v4, v7, etc.).

## Examples

    iex> PhoenixKit.Utils.UUID.valid?("550e8400-e29b-41d4-a716-446655440000")
    true

    iex> PhoenixKit.Utils.UUID.valid?("not-a-uuid")
    false

    iex> PhoenixKit.Utils.UUID.valid?(123)
    false
