chore(debug): add Compose composition tracing deps (debug-only)

Browse Source 
Adds androidx.compose.runtime:runtime-tracing and tracing-perfetto so
recompositions show up as named slices in Perfetto system traces — the
tool used to attribute the cold-start feed first-paint cost to specific
composables. debugImplementation only (not shipped); all Apache-2.0.
Usage (runtime-enable broadcast) documented inline.
