fix(signals): a projection's reader pulls the derive it reads through (#4782) (#4796)

pullFamily's settled branch read the derive untracked, which wakes a lazy
node but does not refresh a stale one, and a leaf carries no height from
its derive. A projection whose derive sits higher (it reads a memo) was
read stale by a lower projection, which then ran again: O(N^2) per flush
since #3774. The pull now makes the pull a tracked read makes: the derive
brought up to date, the reader lifted above it.
