parakeet-cli and parakeet-server have no --version / -V flag #36

Problem

Neither parakeet-cli nor parakeet-server implements a --version (or
-V) flag. Running parakeet-cli --version prints the usage/help text
instead of a version string.

$ parakeet-cli --version
usage:
  parakeet-cli info <model.gguf>
  parakeet-cli transcribe --model <model.gguf> --input <wav> ...
  ...

Why this matters

Packagers (Arch Linux AUR, and likely other distros) verify that a built
binary reports the same version as the source tag it was built from, as a
stale-source-cache detection mechanism. Without --version, the only way
to confirm the embedded version is to inspect git state at build time,
which is not available after installation.

Request

Add a --version / -V flag to both parakeet-cli and
parakeet-server that prints the project version (ideally matching the
release tag, e.g. parakeet-cli 0.3.2). If the version is not already
embedded at compile time, consider injecting it via a CMake
-DPARAKEET_VERSION=... define so the flag works on installed binaries.
