1099 paths as individual Strings measured 182 KB of internal DRAM
resident (each alloc is under the 16 KB SPIRAM-malloc threshold), a
main contributor to the DMA-pool exhaustion behind the :gl crash. The
walk now appends into one newline-joined String seeded at 64 KB so it
and its growth land in PSRAM; the editor stores the blob plus sorted
byte spans (set_file_list_joined) and the palette reads slices. :enew
appends to the blob; :delete drops only the span. Also log the :gl
dirty-journal gate, which looked like a silent no-op on the serial log.
