docs: app.rs is ~8k lines; install delegates to ccebuild

src/app.rs is 8046 lines, not ~5.4k — it has grown by half since the figure was
written, which matters for a number whose only job is to say "this is the big
one, expect to navigate it". And `make install` runs
`ccebuild install --no-build cce-designer` rather than dropping a release build
into ~/.local/bin.
