fix(installer): execute install/update/uninstall ops in execute_batch

execute_batch only awaited prepare(), leaving the install/update/
uninstall + cleanup + repo.write promise chain as a todo!() stub, so
packages were downloaded to cache but never installed into the target
directory. Wire the operation step (mirroring PHP's promise chain),
propagate errors from the install/update/uninstall wrappers instead of
swallowing them with .ok()?, and write the repo after each op.

Un-ignore the create-project functional tests and the install/remove
command tests this unblocks. The remaining --no-install case still fails
on a separate install-path bug; its ignore reason is updated to match.
