Rotate AI idle suggestions with optional remote packs, move history/dictionary onto self-sizing Home preview cards, harden clipboard capture/prompting, and simplify keyboard chrome by dropping most liquid-glass shadows.
Replace MLX GPU inference with CoreML bundles so transcription continues
while the host app is backgrounded. Adds model download and warm-up,
vendored Qwen3Speech, and updates onboarding, settings, and copy for the
~1.6 GB CoreML package (iOS 18+).
The macos-14 runner image no longer ships Xcode 16.0; the default
is now Xcode 16.4. Pin the runner to that version explicitly so
`xcode-select -s /Applications/Xcode_16.4.app` succeeds.
Also drops the build matrix `xcode` field, since the runner only
has one Xcode available and we do not test across multiple Xcode
versions on the audit/appstore-prep branch.
