Terminal viewport collapses into top-left corner with visual tearing after switching between Sessions and Canvas tabs #44

What happened

When switching between an active terminal session and the Canvas tab, the terminal viewport fails to re-fit or re-render upon returning to the session. The terminal shrinks into a narrow band in the top-left corner with visual tearing, leaving the rest of the terminal pane black and unusable.

Expected: The terminal should retain its full layout or re-fit smoothly when switching back to the session tab.
Workaround: Slightly resizing the enowX application window forces Electron to re-render, immediately fixing the terminal.

Steps to reproduce

1. Open an active project session in enowX with OpenCode/terminal running.
2. Switch to the Canvas tab in the top navigation bar.
3. Switch back to the active Sessions tab.
4. The terminal viewport collapses into the upper-left corner with horizontal rendering artifacts.
