[command] Respect raw output when rendering DevTools banner

[coisa]

Summary

Implemented a central logo rendering decision in the DevTools console entrypoint and applied it so command output uses the ASCII banner only for non-raw flows.

Changes

• Added central shouldRenderLogo() logic in DevTools to compute logo visibility from command name and options.
• Added explicit raw-output command suppression for changelog:next-version and changelog:show, which previously relied on raw output contracts and now do not print banner.
• Added option-based suppression for --no-logo, --json, and --pretty-json before any output rendering.
• Updated unit coverage around run-time behavior in tests/Console/DevToolsTest.php to validate that raw changelog commands skip the logo.

Testing

• Focused tests: vendor/bin/phpunit tests/Console/DevToolsTest.php.
• Additional verification: existing targeted command tests for changelog JSON/raw behaviors in the suite.

Review note

Logo gating is centralized in DevTools::doRun() via shouldRenderLogo(InputInterface $input).

Closes #277

Implementation note: raw/changelog-raw behavior is now controlled at the command-boot layer (isRawOutputCommand) so each command avoids per-command output flags and remains orchestrator-safe.
