fix(DiscoveryMountain): resolve crash after install – missing symbols, PSRAM, fetch non-blocking

- manifest V1 -> V2, vendor cJSON, replace roller with dropdown, qsort -> bubble, font -> lvgl_get_text_font
- fix memset(&G,0,0) -> sizeof(G)
- move network I/O off LVGL thread to fetch_task (16384 stack) with PSRAM buffers, raw lwIP sockets HTTP/1.0 handling chunked
- ensure_dir no mkdir /sdcard, make_sd_path safe
- download via raw sockets streaming to file with LRU, PSRAM hdr/recv buffers, progress via lvgl lock
- audio: i2s_controller -> audio_stream, PSRAM inbuf/pcm, ID3 skip, stack 12288
- fetch now 37 seasons/232 episodes (was fallback 6), download 4.3MB OK
- add CRASH_ANALYSIS.md
