Build the Ganjoor reader on the static ganjoor-data set

Poets grid, category browsing and a poem reader backed by
github.com/anas-rashid/ganjoor-data over jsDelivr — no backend, addressed by
Ganjoor URLs rather than numeric ids, with a 64 MB OkHttp disk cache so
anything already read stays readable offline.

Reading: couplets stack with the first hemistich at the start of the line and
the second at the end; prose sections fill the column. Bundled Noto Naskh
Arabic and Noto Nastaliq Urdu, switchable while reading, with the extra
leading nastaliq needs. Five themes (system, light, dark, sepia, sepia night)
and a text size slider, all persisted. Whole app lays out right-to-left.

Verified on an API 36 emulator through poets -> category -> poem in both
sepia schemes and both fonts.
