mobile-build.md:
- Removed "PedsHub Quiz" sections. That app lives in a separate
repo (quiz/mobile/) and has its own build pipeline. Docs here
are PedScribe-only now.
- Reorganized around CI as the primary flow, local build as
fallback. Added explicit secret names, JDK requirement, single-
quote-password caveat, QEMU/argon2 note.
- File-map section at the end so the native sources are
discoverable without grepping.
CONTRIBUTING.md:
- Cut the narrative prose. Dev-facing tables + single-line
commands only. Decision-tree removed (the table suffices).
- Release pipeline and mobile build link out rather than
duplicating content.
