drive pc: render pseudocode in the TUI, not just the driver

The pc command called only the read-only pseudocode RPC (runs off the UI
loop, never touches the screen), so LLM-driven sessions showed nothing on
the live pane. Compose goto + toggle_view + search so the real TUI
navigates to the function, makes the decomp pane the visibly-active view,
and jumps the cursor to the needle — then return the same text as before.
