openarch 0.9.0、两个板级包的 run 档 (#342)

`mcpplibs.openarch@0.9.0` adds an ARMv7-A backend, and with it the answer to a
question the layer's three original machines could not ask. All of them are
64-bit with 64-bit page-table entries, and `pte_encode.h` recorded that as a
fact about every machine there. ARMv7-A's short-descriptor entry is 32 bits.

The value fits in the `arch_u64` the interface carries, so the carrier did not
change; what was missing is a way to ASK for the storage width. A kernel sizing
a table from `sizeof(arch::pte)` builds one twice as large as the hardware
walks, and nothing diagnoses it — the table is well formed, the entries are
correct, and the machine reads the gaps. `arch_pte_entry_bytes()` is the answer
and every backend implements it.

Cortex-M could not settle this: it is a 32-bit machine with an MPU and no page
table, so its pte group exists and refuses. A 32-bit machine WITHOUT paging
leaves the question where it was.

`openarch:preemption` is withheld on armv7a, by the mechanism Cortex-M already
uses to withhold `openarch:address-space`: the resumption address lives on the
SVC stack rather than in a register, so a trap-time switch is well defined only
if the resumed context was suspended the same way, and that is not a design this
backend has measured.

`mcpplibs.riscv-virt-rt@0.7.1` and `mcpplibs.aarch64-virt-rt@0.2.1` move their
emulator onto the `run` tier. The untiered form meant `Always`, so a CI job that
compiled firmware and never ran it downloaded 33-36 MB of emulator for nothing.
The engine has had `when` since 2026.9.4.2 and `cortex-m-rt` adopted it; these
two had not, which left one batch with two spellings.

Audited before submission: 37 versions, 74 URLs fetched and hashed against the

path dependencies.
