default to the pseudocode view instead of disassembly

Opening a function now shows the decompiler by default (Tab still toggles to
disassembly; the choice persists across opens). Startup focuses the decompiler
view, and Ctrl+B / back focus the active view rather than hard-coding disasm.

Tests: assert pseudocode-by-default on the first open, then normalize per-section
(the disasm-scrolling/search/follow blocks switch to disassembly explicitly).
full suite 75/75.
