Feature: add --version flag to clawrtc CLI

Feature request: add --version to clawrtc CLI

Problem

clawrtc currently shows help and subcommands, but there is no direct version flag in the CLI UX on many installs. This makes quick environment checks and support debugging slower.

Requested behavior

Add a standard version command output:

• clawrtc --version
• (optional) clawrtc -V

Expected output format example:

clawrtc 1.6.0

Why this helps

• Faster support triage
• Easier bug reports (users can paste exact CLI version)
• Standard CLI ergonomics matching common tooling

Suggested implementation

In clawrtc/cli.py, add argparse version action using package __version__, e.g.:

parser.add_argument("--version", action="version", version=f"clawrtc {__version__}")

Thanks.

Good feature request! The --version flag should report the installed version from package metadata. We'll get this into the next release. Note: xiangshangsir has submitted PR #507 attempting to implement this — we'll review it for quality.
