Rewrite the three sp5_budget_c51/cql/ens registry descriptions to be
accurate at HEAD aa2854017: replace present-tense "driven by"/"no longer
writes" with future-tense "will be driven by"/"will stop writing", replace
non-existent C51_BOOTSTRAP_BUDGET/CQL_BOOTSTRAP_BUDGET/ENS_BOOTSTRAP_BUDGET
named constants with their actual anonymous .max() literal line references,
and apply the "(Pearl 2 will stop writing...)" parenthetical uniformly to all
three slots (cql was missing it). Audit doc T2 bullet updated accordingly.
