Deviation from Plan 02: the JVM mockable-android.jar stubs every Cursor
method even with isReturnDefaultValues=true (returns null/0 regardless of
the underlying MatrixCursor backing). Introduce an internal ColumnReader
interface so mappers stay pure-Kotlin and JVM-testable via MapColumnReader,
while production reads through CursorColumnReader.
CalendulaApp registers the Hilt component graph. MainActivity uses
enableEdgeToEdge() and renders a centered placeholder showing app
name + tagline via CalendulaTheme. PlaceholderPreview lets the IDE
preview the layout. Resolves the pre-existing MissingClass lint
error from the manifest reference.

CalendulaSeed (0xFF5C6B7A) anchors the design palette. Theme picks
Dynamic Color on API 31+ when enabled (default true) and falls back
to a hand-tuned Light/Dark scheme otherwise. CalendulaTypography is
the M3 Expressive default for V1 - custom type scale lands in a
later UI-design iteration.
ColorSchemeTest pins the seed value (3 unit tests, all pass).
