FlorianandClaude Opus 4.7 23fc99f0fe [MEM] Heap-allocate createDiscovery JsonDocuments (#2302) 
createDiscovery sits at the bottom of the discovery call chain
(loop → launchBTDiscovery → <device>Discovery → createDiscoveryFromList
(9-col, VLA) → createDiscoveryFromList(13-col) → here). Keeping
2×1024 B StaticJsonDocuments on the stack burned loopTask headroom
down to ~100 B free under a full BLE + WebUI load. Moving the two
buffers to the heap drops that 2 KB off the stack peak.

Measured over the full test_perf + test_webui suite on
esp32dev-ble-hil-fastsys (dev HEAD):

  freestck_min_bytes: 292 → 2324 B   (+2032, target was ≥1500)
  minmem_soak_bytes: 18200 → 20652 B (+2452)
  all 17 tests still pass

The docs are function-scoped, so net heap usage is unchanged long-term
(free-on-return), and the soak heap floor actually improved.
