Branch picker now handles Escape key to dismiss, shows an × close
button in the header, and displays error/empty states instead of
silently showing nothing. Dialog backdrop is click-to-dismiss (the
dialog content stops propagation so clicks inside don't close it).

Single Flutter package at the repo root. All code, tests, assets,
and platform directories moved from app/ to root. Package renamed
from clide_app to clide — all imports rewritten. Merged pubspec
combines core (ffi) and app (flutter, yaml, xterm) dependencies.
Makefile simplified: no APP_PRESENT conditionals, no cd, no daemon
lifecycle. 317 tests pass.
