feat(ci): freeze the conftest save/restore inventory so it can only shrink (#37621)
* feat(ci): freeze the conftest save/restore inventory so it can only shrink

* fix(ci): resolve the named constant a conftest save loop iterates

* fix(ci): match the snapshot shape instead of a list of blessed dict names

* feat(ci): fail a branch that clears TQ violations without lowering the ceiling

A limit that only ever falls is not the same as one that falls when it can.
Clearing violations and leaving the ceiling above the new count let the same
violations return later under a limit nobody moved, so the gate now fails on
that and names `make lint-budget-update` as the fix. It needs both head below
base and head below limit, so headroom already in the base is never blamed on
the branch that happens to run next.

Drops the seeded-rule exemption from the ratchet along with it. Its stated
reason was that the base tree predates a rule introduced on this branch, but
base counts are measured with the current checker, so such a rule is counted at
the base too and its grandfathered total was never at risk of reading as fixed.
Removing the exemption is what lets a newly seeded rule ratchet like the six
that came before it.

The base scan is skipped when the branch touches neither the test tree nor the
checker, since neither count can have moved.
