Bump version to 0.0.8 and add changelog covering the work since the
unpublished 0.0.7: gesture command coverage + iOS transform gestures,
precise location settings, platform alerts, scroll-to-edge, the iOS
runner content-fingerprint staleness cache, device-enumeration skip,
CLI negative-positional + clean --json fixes, and the npm head-to-head
benchmark harness.
