BullMQ version information.

This module contains the BullMQ version that corresponds to the Lua scripts
being used. This version is stored in Redis to indicate queue capabilities
and is used by frontends (like Bull Board) to match features.

**Important:** This version tracks the Lua script compatibility with the
Node.js BullMQ library, NOT the Elixir package version. The Elixir package
version is defined in `mix.exs` and can evolve independently on Hex.pm.

## How it works

When a Queue or Worker interacts with Redis, the BullMQ version is stored
in the queue's meta hash. This allows:

- Frontends to know which features are available
- Different clients (Node.js, Python, Elixir) to interoperate
- Backward compatibility checks

## Version Format

The version stored in Redis follows the format: `bullmq:<version>`

For example: `bullmq:5.65.1`

# `full_version`

```elixir
@spec full_version() :: String.t()
```

Returns the full version string as stored in Redis.

## Examples

    iex> BullMQ.Version.full_version()
    "bullmq:5.65.1"

# `lib_name`

```elixir
@spec lib_name() :: String.t()
```

The library name used in the version prefix.

# `version`

```elixir
@spec version() :: String.t()
```

Returns the BullMQ version string.

## Examples

    iex> BullMQ.Version.version()
    "5.65.1"
