pql is now a bare word on PATH, which removed the long incantation that had
been forcing --vault into every call by habit. Convenience lowered the cost
of the wrong thing without lowering the cost of the right one: a three-word
pql ticket new targets whichever vault the cwd happens to sit in, and there
are nine of them with colliding id sequences.
PQL_VAULT in each project settings file makes the vault a property of the
session rather than of the working directory — the same lesson Rule 3 records
for git -C, applied to pql. Verified the env var overrides cwd discovery,
that an explicit --vault still beats the env var, and that the harness
hot-reloads it without a restart.
This does not make provenance visible: no output says which vault answered,
so a forgotten --vault still returns a well-formed answer about the wrong
dataset. That remains T-37.
