docs(qa): retarget rollup-summary-filter editor half at duplicate route (#11913)

automation.rollup-summary-filter clause 5 (the visual filter-editor half)
was blocked.by:fixture, tracked at #3358. The maintainer ruled NO on a
stock writable showcase package (2026-08-19, 「接受你的所有建议」) and
directed retargeting at the platform's own runtime path instead: the
runner clones the showcase base into a writable target via
POST /packages/:id/duplicate (ADR-0070 D4 "duplicate base").

Bumped revision to 3 with a history entry; removed the item-level
blocked.by:fixture entry and its matching fixtures.knownGaps line, since
the clause is runnable on every boot now. Oracle stays screenshot — the
clause specifically exercises the visual editor, corroborated by a
meta-API read of the persisted filter.

The sibling half (access-security.json, readonly-package-locks-studio)
is held by open PR #11780 and stays out of scope here — see the PR body
for the card relationship.
