Houston v0.4.28

Houston 0.4.28

Fixes

• GPT-5.6 models can use their code tool again. Missions where Sol, Terra,
  or Luna tried to run code failed with an error. A missing piece now ships
  with the app on Mac and Windows, so those missions complete normally.
• Commands show up while they run. When an agent on a GPT model runs a
  command, the mission log now shows it in progress instead of only showing
  the result at the end.

Before you upgrade

• Mac: quit Houston before installing. macOS does not always replace a
  running app cleanly. If in doubt, remove /Applications/Houston.app and drag
  the new copy in.
• Windows x64: auto-update from 0.4.7 or later pulls you forward
  automatically. The MSI is still not OS-code-signed, so Windows SmartScreen may
  warn on a fresh install.
• Windows ARM64: there is no auto-update path from an emulated x64 install.
  Download the ARM64 MSI manually, uninstall the x64 build first, then install
  the ARM64 one.
