a## Summary

Bumps Flick to 0.23.2-beta.4+33 and publishes the release record for the landscape, tutorial, Spanish, orbit, metadata, and audio work since 0.23.1-beta.3.

• Updates pubspec.yaml, kAppVersion, and kAppBuild in lockstep.
• Adds the 0.23.2-beta.4 (2026-11-10) section to CHANGELOG.md, covering Spanish, Taglish UI Customization, the route-aware tutorial, landscape and orbit layouts, card backgrounds, progress-bar sizing, SAF metadata write-back, the physical-output volume guard, DSP telemetry, and SMB resilience.
• Adds a matching What's New entry, so the first launch after updating surfaces the same notes.
• Adds docs/RELEASE_0.23.2-beta.4.md with the release copy, flavor differences, and Getting Started steps for the new settings.
• Updates docs/RELEASING.md to the current version code.
• Moves the SMB entries that had been listed under 0.23.1-beta.3 into 0.23.2-beta.4, matching the release they actually ship in.
