Splits the census's query class into **read-shaped** (convertible) and
**write** (must not be converted), reported beside the existing total.
On current `main`:
```
QUERY filters (column: "<legacy>"): 63
of those: 48 read-shaped (convertible), 5 writes (do NOT convert), 10 other
```
## Why the single number misleads
`column:` sits in an options-shaped object for both a source query and a
write, so the existing definition-vs-query rule cannot separate them.
The result reads as "dead reads to convert" — and after #2818 landed,
**48 of the 63 are `self-healing.ts` and the rest are largely not
convertible at all.**
Converting a write in this class is **harmful, not merely pointless**.
`async-persistence.ts` soft-deletes with `.set({ column: "archived",
deletedAt, … })`, and `getLiveTaskColumn` returns `"archived"` as a
**sentinel** for any soft-deleted row — the write and the sentinel have
to agree. A sweep that "finished the query class" by converting all 63
would break live-column resolution for every deleted task.
That is the same shape #2808 flagged for `recoveryRehome` moves. **Two
of the census-invisible classes now have members that must not be
fixed**, and in both cases the count alone cannot tell you which.
## Reported, not ratcheted
`properties.query` and `queryByFile` are byte-identical, so the pinned
baseline does not move and no open PR's Lint changes. The split is one
extra line of output.
**Changing what a ratchet enforces is the owner's call; improving what
it says is not.** Same line I drew when making marker-only failures
legible without loosening them.
## Honest limit
Read-shaped is a better filter than the raw count and **still not a
verdict**. `auto-merge-finalization.ts:242` is classified read-shaped
and must NOT be converted — its own comment records that it is
`getTaskHardMergeBlocker`'s review-eligible sentinel, deliberately not
re-keyed. Nothing mechanical would catch that; only the comment beside
it does. The split narrows a haystack to a readable list; it does not
decide the list.
## Verification
4 new cases — a `listTasks` filter counts read, a `.set()` tombstone
counts write, IR node definitions stay excluded from the class entirely
(the pre-existing rule must keep working), and the pinned total is
unchanged by the split. Revert proof: dropping the write branch fails
the tombstone case.
Census's own suites **87 passed**, gate **161 / 13 / 487 / 71**, lint
clean, `--strict` exits 0.
