* refactor(apple): colocate the XCUITest runner client into packages/platform-apple (#2040)
Moves src/platforms/apple/core/runner/ (34 modules + apple-runner-platform.ts and
the 30 runner test suites) into packages/platform-apple/src/runner/ — Apple
mechanics live in the Apple package. Host capabilities (exec, diagnostics,
retry, process probes, locks, Apple tooling, physical-device control) enter
through the package-owned AppleRunnerHost port; the root composition module
src/platforms/apple/core/runner-client.ts constructs the client exactly once
and re-exposes the bound operations under their historical names.
R13 admits the transitional state deliberately: the family exports its root
façade plus exactly the enumerated ./runner, ./runner/client, and
./runner/test-host subpaths; the ./runner façade subpath is the recorded #1983
seam for unmigrated root consumers; ./runner/client has one composition root
and ./runner/test-host one vitest installer; the runner subtree may own its
cache files and sockets while raw process primitives stay banned. When #1983
completes, the subpaths and every subtree exemption are deleted and the family
returns to a single implementation-lazy façade export.
* docs(adr): model the runner subtree as a durable platform-owned facet
Review correction on #2050: the sunset story attributed the runner-consumer
migration to #1983, which owns snapshot/presentation vocabulary — not the
runner's daemon/root consumers — so that event cannot delete the ./runner
subpaths or the subtree exemptions. Reword ADR-0019, R13, and the gate
comments: the facet is the intended ownership model, its seam is enumerated
and pinned (exact export list, one client composition root, one test-host
installer, raw-process ban, eager-closure pins), and the seam narrows only
if a real runner-consumer migration retires the direct consumers. The
declaration mechanism stays apple-specific until another family needs a
mechanics facet. No behavior change; identifiers and comments only.
