Subject: [PATCH] feat: adaptive launcher icon - '1' on slate squircle
 (kalendae)

Static stylized '1' on a slate (0xFF5C6B7A) background. The numeral
references kalendae, the Latin word for 'first day of the month' that is
the etymological root of both 'Calendar' and 'Calendula'. Adaptive icon
spec: foreground vector path, monochrome variant for themed icons (API
33+), no PNG fallback needed (minSdk 29 > 26).

Visual refinement is expected during the UI design iteration; this is
the foundational shape and meaning.
