[IMP] installation: parallelize repo sync and poetry install

Poetry install and git-repo sync are independent (different write
paths). Running them sequentially wastes time. Split install_locally.sh
into EL_PHASE=setup|poetry|all phases so install_locally_dev.sh can
background the repo sync while poetry runs in the foreground, reducing
total install time by up to 50% on slow connections.

Set EL_PARALLEL_INSTALL=0 to restore sequential behavior for debugging.
