On-device review follow-ups: - Month widget grid is now tappable. Day numbers open that day and event bars open the event's detail, both rooted in the month view so back returns to the grid. Previously only the prev/next/today header controls responded — the grid cells were never clickable. - Pill/drawer view switches now build a visit history instead of collapsing to the default view. Back retraces the views you moved through (a not-yet-visited view is pushed; revisiting one collapses the loop back to it), down to the default, then exits. Widget launches still reset to their own view context. Refs #1, #2 (reported by @devinside). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
