The ADR-045 display probe false-positives on display-less
ESP32-S3-DevKitC-1 boards (SH8601 init 'succeeds' against floating
pins), so main.c skips the RuView#893 MGMT+DATA promiscuous upgrade
and CSI yield collapses to 0 pps. sdkconfig.defaults.devkitc compiles
display support out, making has_display constant-false so the #893
upgrade always applies. Hardware-verified on 2x DevKitC-1-N16R8:
0 pps -> steady 40-45 pps.
Also updates the Quick Start build commands and badge from
espressif/idf:v5.2 to v5.4 — current source uses esp_driver_uart
(IDF v5.3+) and no longer builds under v5.2; CI already uses v5.4.
