Introduce optional Apple account-backed credits with scoped gateway access while preserving local and BYOK paths. Refresh assistant behavior, tests, privacy disclosures, docs, and the website for the 2.0 experience.
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.
