runtime: pin that a disabled host package no longer hides a package-less stored row of a type stored per (package, name) #33035

Source: contract review r2 6845067990 on PR #33006 (card #32812), should-fix S4.

#33006 declares one widening under its BREAKING banner: on a host that declares its package, a package-less stored row of the ten types stored per (package, name) is no longer hidden when the host's own package is disabled. It now behaves as it does on a host that declares no package. #33006 pins the cause in @objectstack/metadata (the served row carries no _packageId), but no package pins the answer itself.

Task: add a pin next to the reader in @objectstack/runtime (the disabled-package filter in src/domains/meta.ts). Do the same in @objectstack/core if its reader can be reached in a unit test. The pin should cover both hosts (declaring the package, declaring none) and expect the same answer on each. Tests only, no source change.

• Size: S.
• Effort: medium.
• Blocked on: fix(metadata)!: the boot priming pass leaves a package-less stored row of a type stored per (package, name) unstamped, so the host's package is never counted as a holder of its name (ADR-0150 D4) #33006 landing. Do not start until it lands.
