Stack v0.2.1

Add a small in-dashboard information screen for checking the running Stack binary.

Information screen

• Press i from the dashboard to see the build version without interrupting service supervision.
• Press i again or Esc to return. q retains its existing quit behavior.
• The screen is available in compact terminal layouts too, and the compact footer now advertises the shortcut.

Upgrade

No configuration changes are required.

brew update
brew upgrade caliluke/stack/stack

Validation

The Go test suite, vet, build, version, and help checks pass. TUI snapshots cover the information screen at wide, narrow, and compact terminal sizes, and a behavior test verifies open and close interactions.
