fix(ios): keep an identifier hook the fold cannot prove inert

[thymikee]

Summary

collectIosStructuralIdentifierSuppression deleted a childless Other wrapper carrying only an
identifier, assuming its content would carry that identifier onward. A childless wrapper has nothing
to delegate to, so the identifier left every canonical view while is, get, and click still
resolved it from the same capture. Whether a wrapper arrives childless is decided by a fact the
producer may not report at all: the Apple runner answers hittable for every node, the Simulator AX
bridge for none. Suppression now requires the node's own declared hittable: false (ADR 0004).

On one screen of one installed app, snapshot -i over both producers now yields identical 18-hook
sets: home-title, gesture-lab-card, drag-gesture-fixture and gesture-metrics are addressable
under Simulator AX, as they already were under XCTest. Refs #2638. Out-of-process surfaces in that
report (PHPicker, MapLibre annotation content) are not this rule and still need raw captures. 7
touched files.

Validation

Tested at 35d1a35f77087f0412b644d49df073d9d45bbe4f.

• pnpm check:affected --run: all runnable checks passed (2163 tests).
• Reverting the rule turns exactly two tests red: the rule case in noise.test.ts and
  daemon-runtime-port-identifier-hook.test.ts. The delegation case and both negatives stay green;
  they pin unchanged behavior.
• Live, iPhone 17 Pro, iOS 26.2, examples/test-app: snapshot -i --json identifier sets identical
  across producers (18 vs 18, none one-sided); a Maestro flow asserting home-title then
  gesture-lab-card reports 1 passed; is visible 'id="home-title"' passes.
• A live off-screen negative was unreachable because this Home list ignores synthesized scrolls, so
  it is pinned at the adapter seam.

Risk: a bridge capture has no occlusion signal, so a hook behind an in-app modal can read visible —
predates this change, covers every bridge node. Sessions closed; simulator 2638-verify left booted.

Reviewed at 35d1a35. The fold now suppresses a childless identifier-only wrapper only when the node itself declares hittable: false, so a producer that reports no hittability keeps the hook addressable. The new daemon-route test goes red without the guard, because a suppressed wrapper maps to no presented node and reads as not visible. The live snapshot -i comparison over both producers in the PR body covers the changed path.

Smoke Tests fails on RunnerTests.testAlertAcceptDoesNotActivateAReplacementWithASharedButton, a runner XCTest for alert activation. This diff changes no Swift or alert code, so the failure looks unrelated. There are no conflicts. Next: human review.
