release: ship v1.5.0 with on-device writing suggestions

Adds next-sentence suggestions while typing, weekly input insights and a
personal phrase memory to the desktop app, and fixes custom instructions so
they process the text instead of inserting the instruction's own wording.
Local model requests are now bounded and individually cancellable.

Bumps the product version to 1.5.0 (Android/iOS build 1050000), refreshes the
landing and web download links, and records the new INPUT feature rows and the
open verification gaps in the infrastructure map.
