* refactor(apple): drop dead runner code and collapse duplicated helpers
Removes declarations with no consumers (findScopeElement, interactiveTypes,
two unused PresentedNode convenience inits) and collapses copy-pasted logic:
DataPayload now relies on the synthesized memberwise init, TvRemoteButton is
String-raw-valued, point-hit sorting shares smallestElementFirst, command-id
trim-or-nil lives once on RunnerCommandJournal, scroll/desktopScroll share
direction and durationMs validators, and the seven inline NSError refusals use
unsupportedOperationError. elementTypeName reads a table pinned by the
visibility-fold parity test.
The packager now skips files whose unit-test blocks were their whole body, so
10 test-only files stop shipping (and stop compiling on user machines) as
empty translation units.
Packaged Swift: 432.3 kB -> 427.8 kB; 56 files instead of 66. Net -144 lines.
* test(apple): pin skeleton-file exclusion in the packaging guard
The strip fixture always kept runtime content, so reverting the
skeleton-skip branch left every guard green. The new fixture's whole body is
unit-test blocks; the packaged path must be absent while a non-skeleton
sibling still ships. Observed red with the skip branch disabled before
re-enabling it.
* refactor(apple): tighten runner cleanup boundaries
Every declared AgentDeviceRunnerUITests method now belongs to a lane, and
the #if guard is the classification: AGENT_DEVICE_RUNNER_UNIT_TESTS alone
means a pure runner decision (runs on the macOS host on every PR — ci.yml's
existing compile job now executes the bundle it builds), '&& os(iOS)' means
runner/XCTest semantics (simulator lanes only). check:xctest-selection
evaluates the guards per platform, derives each lane's reach, and fails on
a flagged identifier that is undeclared or uncompiled on that lane, on a
declared test no lane reaches (found the two tvOS-only tests, dark since
birth — widened to os(tvOS) || os(macOS)), and on testCommand reaching any
lane. The host and nightly lanes assert executed == derived reach, so a
missing -D flag or a guard that compiles a file out reads red, not as a
smaller green. One duplicate test deleted (sparse-verdict assertions folded
into its twin).
