Make console --info safe for ordinary and packaged builds

[TheAngryByrd]

What to build

Make the generated console --info command return useful output after ordinary builds and release packaging.

Current behavior

Ordinary builds omit release metadata. The command uses Seq.find and throws System.Collections.Generic.KeyNotFoundException when metadata is absent.

Acceptance criteria

• Read release metadata as optional values.
• Display unreleased when the release date is absent.
• Display unknown when the Git hash is absent.
• Return exit code 0 after an ordinary build.
• Display supplied metadata after a release build.
• Return exit code 0 from a packaged artifact.
• Preserve existing --version and main-command behavior.

Blocked by

• None — can start immediately.
