fix(kvb-org-organize): no hook runs a binary planted on the inherited PATH

Hooks run outside the sandbox but inherit a PATH whose directories
sandboxed agents of the same uid can write (a virtualenv's bin activated
first by the shell profile), so a file planted there under the name of
docker, git or notify-send ran unsandboxed. hookpath.py keeps only the
PATH directories that, with every parent, belong to another uid and that
neither group nor others can write, as real paths; inside the sandbox's
user namespace root shows as the overflow uid and still counts as sealed.
watch.py, radio.py and council.py set that PATH before they start
anything, and the cleanup child runs with -I. Both reminder hooks pin
PATH=/usr/bin:/bin, and the install registers them with /usr/bin/bash and
moves older bare bash and python3 entries to the absolute paths.
