Fix docs-builder version output

[theletterf]

Why

docs-builder --version was reporting the CLR assembly version (1.0.0.0) instead of the semantic release version shown by older releases.

What

Handle the fast --version path before Argh's intrinsic handler and print the assembly informational version, falling back only when that metadata is unavailable.

📝 Walkthrough

Walkthrough

This PR adds early explicit handling for the --version command-line argument in the docs-builder entry point. Before constructing the service host, the program now checks for --version, extracts the executing assembly's informational version attribute (falling back to assembly version or "unknown" if unavailable), writes it to stdout, and exits immediately. The System.Reflection namespace is added to support version attribute lookup, and the pre-host fast-path comment is updated to reflect this new behavior.

This needs fixing in upstream nullean/argh

Closing this local workaround in favor of fixing the version source in Argh itself.
