Marc-André Bombeck d49479bc64 Pin where the Coach stops checking its own numbers ...

Three characterisation tests for grounding gaps found while verifying that
every figure the Coach states comes from the record.

The numeric grounding guard rewrites any figure the turn's Grounding Ledger
cannot account for, and it holds: removing the strip reddens the existing
cross-turn ledger test. What is not covered is its activation. On the tool
path the guard runs only when `loop.toolResults` is non-empty, and a tool that
found nothing resolves to `{ present: false, reason: "none" }` with no
`available` payload, which the loop drops. So the guard disarms itself exactly
when the record is empty: ask about a metric with no readings, and an invented
figure is persisted and streamed verbatim, with no withheld-figure marker to
tell the reader it was never checked. The no-tools snapshot fallback is
populated only in the non-tool-mode branch, so the tool path has nothing to
fall back to, and every cloud provider runs the tool path.

Separately, a rollup bucket outlives the rows it was folded from. The read-swap
falls back to live SQL only on an empty band, `ensureUserRollupsFresh` repairs
the DAY tier over the trailing 90 days only, and it keys off
`Measurement.updatedAt`, which a hard delete does not bump. The integration
test reproduces the hard `deleteMany` in the WHOOP body sync against a
MONTH-band bucket: the deleted value keeps reaching the Coach's coarse tail
while the all-time extremes beside it report only the surviving value, and the
block is stamped current because `asOf` is derived from raw reading age and
knows nothing about rollup age.

All three assert current behaviour and carry a docblock saying so. Closing
either gap will redden them, which is the point.
