* ci: run PR unit shards on free hosted ARM as 12 shards
Enterprise's 1,000-job limit makes more, smaller shards free. A 12-shard
cold run on ubuntu-24.04-arm measured 361s median / 412s max per shard,
against ~390s / ~441s for five warm Blacksmith 8-vCPU shards.
The Blacksmith-store module cache producer becomes dispatch-only since
hosted shards cannot read it.
* TEMP: force 12 shards on this PR (repo var is still 5); drop before merge
* test: size the full-inventory routing check from FULL_SHARD_COUNT
* Revert TEMP 12-shard override; the repository variable is now 12

* ci: restore main's Vitest transform cache in PR unit shards
Main produces per-shard transform caches on a schedule; PR shards restore
the newest one for the same config/lockfile/runtime policy. A Vitest cache
key generator folds each literal specifier's resolution candidates into the
per-module key so newly added files that shadow a resolution invalidate the
importer, and bails on glob-expanded dynamic imports.
* ci: list the resolution key plugin in the node tsconfig project
* ci: accept Vitest's CACHEDIR.TAG when sealing the unit module cache
Vitest 5.0.5 tags its cache root, which made every seal fail with
'invalid cache entry name' so no producer cache was ever saved.
* ci: reseed the unit module cache when any cache-key input lands on main
