feat: Support archived repo exclusion from GH org scans

[hibare]

Description:

Adds optional exclusion of archived GitHub repositories from organization scans. Introduces the --exclude-archived flag on the github subcommand, a matching exclude_archived field on the GitHub source protobuf (sourcespb.GitHub), and wiring through GithubConfig, the engine, and org repo enumeration so archived repos are skipped when the option is enabled. Default behavior is unchanged when the flag is not set. Includes unit tests, an integration test case, and README usage.

Checklist:

• Tests passing (make test-community)?
• Lint passing (make lint this requires golangci-lint)?

Archived repo counter incremented only when not excluding

Low Severity

The numArchived counter is placed after the continue statement inside the ExcludeArchived check, so it's only incremented when archived repos are included (not excluded). When ExcludeArchived is true, repos are skipped via continue before numArchived++ runs, making the final log line always report num_archived=0 — exactly when you'd most want to know how many were skipped.

This behaviour is inline with how numForks is counted.
