iter20-26: kernel-side root-cause localization, α-25/α-26 fix Bug 4, partial Bug 5
iter20-23: kernel printk in rkvdec_hevc_run + v4l2_ctrl_request_setup
iter24: pinpointed rkvdec_s_ctrl returning -EBUSY for HEVC_SPS due
to vb2_is_busy(CAPTURE) — libva pre-allocates 24 CAPTURE bufs
before first per-frame S_EXT_CTRLS, blocking image_fmt reset
iter25 α-25: synthetic SPS injection before cap_pool_init seeds
ctx->image_fmt to RKVDEC_IMG_FMT_420_8BIT while CAPTURE is
still empty. H264 Bug 4 fully fixed (byte-equal kdirect).
HEVC Bug 5 frame 1 fixed (byte-equal kdirect).
iter26 α-26: populate decode_params.short_term_ref_pic_set_size from
picture->st_rps_bits (VAAPI does expose it). Bytes 4-5 of
dp now match kdirect. HEVC frame 2+ still diverges
(separate bug, likely DPB entry mapping).
