jpmschweitzerandClaude Opus 4.8 67de636ab4 Fix DSI blue flicker under load: lower DPI clock to 40 MHz
The blue flicker during voice activity is a MIPI-DSI framebuffer-read
underrun on the PSRAM bus, not tearing. The DSI DMA reads the 800x800
framebuffer continuously (~138 MB/s at the stock 80 MHz clock); under
load the Wi-Fi (esp-hosted SDIO) and audio-playback DMA on the same
PSRAM bus starve the DSI FIFO, which the hardware then paints blue
("lcd.dsi.dpi: can't fetch data from external memory fast enough").

Drop the DPI pixel clock to 40 MHz (~54 fps): halves the continuous
read and gives the FIFO slack to ride out bursty SDIO latency spikes.
Still smooth for the face UI, and lowers display power.

Vendored as a local component because managed_components/ is gitignored
(same pattern as the esp_hosted fork) — a local component overrides the
same-named waveshare/ managed dependency, so the fix survives a clean
build.
