Adolfo be9229b80d refactor(DiscoveryMountain): split monolithic main.c into modular files
- Extracted app_context (global AppCtx G definition)
- storage: path helpers, LRU, sort, fmt_time, per-episode resume map, state persistence
- network: resolve_host, normalize URL, http_get_raw with growing PSRAM buffer, fetch_data
- download: dl_ep_raw with progress tracking, cancel, overlay UI (show/hide/update)
- player: audio device, stream, play_task with resume seek, start/select/next/prev with position save/restore
- ui: build_ui, timers, season picker, button callbacks, periodic save
- main: minimal glue, fetch_task, onShow/onHide, app registration
- Preserves all previous fixes: download progress overlay, per-episode resume, robust download handling
- Build verified: 111 undef, all exported
