Automated release from CI pipeline

Changes:
fix(firmware): add vTaskDelay(1) yields in process_frame() at tier>=2 to fix WDT storm (ruvnet#683)

At edge tier>=2 on N16R8 PSRAM boards, process_frame() runs
update_multi_person_vitals() (4 persons ×ばつ 256 history samples) plus
wasm_runtime_on_frame() back-to-back before returning to edge_task().
The existing vTaskDelay(1) in edge_task() only fires after
process_frame() returns — under sustained 30 pps CSI load on PSRAM
boards this leaves IDLE1 on Core 1 starved long enough for the 5-second
Task Watchdog Timer to fire.

Fix: add two vTaskDelay(1) calls inside process_frame(), both gated
on s_cfg.tier >= 2:

1. After update_multi_person_vitals() (Step 11)
2. After wasm_runtime_on_frame() dispatch (Step 14)

Tier 0/1 paths are unaffected. Validated on COM7 (N16R8 board):
Edge DSP task started on core 1 (tier=2), no WDT panics in 20 s.

Also bump firmware version 0.6.5 → 0.6.6 and refresh all 6 release_bins
with the new build (8MB + 4MB variants, built 2026年05月21日).

Fix-marker RuView#683 added to scripts/fix-markers.json.
