Summary
Align firmware ESP-IDF version references to v5.4 (fixes #1177 build error).
Why this matters
Issue #1177 reports an ESP32 firmware build failure:
undefined reference to '__ieee754_sqrtf'when building the CSI-node firmware (commit 7831f29, v0.8.2-esp32) with ESP-IDF v5.3 / xtensa-esp-elf 13.2.0 on Apple Silicon. The owner (ruvnet) replied three times that the project is tested against and targets ESP-IDF v5.4, and that v5.2/v5.3 are missing math stubs (__ieee754_sqrtfis pulled in by thesqrtfcalls inmain/edge_processing.c), so the fix is to build with v5.4. The root cause on the repo side is a stale documentation inconsistency: the firmware README quickstart still instructs users to build with theespressif/idf:v5.2Docker image and carries an "ESP-IDF v5.2" badge, andTesting
Changes are scoped to the files named in the fix; added or updated tests where the project has a suite, and matched existing conventions.
