icons: default to ~/projects/cce, the workspace's new home

The tree moved out of ~/Dropbox on 2026-08-27 — 432k of its 444k files
were cargo build artifacts, so Dropbox spent its time re-hashing a
directory that regenerates itself. This default was the only path in
the toolkit that assumed a checkout location; $CCE_ICONS_DIR still
overrides it.
