share .pql/hooks/ across clones

The pql plan auto-export (pre-commit) and auto-import (post-merge)
hooks were previously gitignored as part of `.pql/*`. Allowing the
hooks directory to be committed means a fresh clone gets the
planning-state sync without needing to run `pql init` first — pql
plan snapshots stay current on push and absorb changes on pull
the same way for every contributor.
