enricobuehlerandClaude Fable 5 5a27c02738 feat(encode/nvenc): LN1 phase-0 — slice-count + sub-frame-readback knobs and the slice-timing probe
PUNKTFUNK_NVENC_SLICES=N (2..=32, default off) splits H.264/HEVC frames
into N slices (sliceMode 3); PUNKTFUNK_NVENC_SUBFRAME=1 (default off)
arms enableSubFrameWrite + reportSliceOffsets on sync sessions only.
Both experimental groundwork for sub-frame slice output (plan §7 LN1).

nvenc_cuda_subframe_slice_probe (on-hardware, ignored) answers the LN1
go/no-go: spins lock_bitstream(doNotWait) against an in-flight frame and
prints the (t_us, status, numSlices, bytes) timeline — incremental slice
availability and its spacing, or all-at-completion.
