Follows PR #26 (Intra_4x4 luma) with the same promotion pattern for
the rest of the intra prediction primitive set:
Intra_16x16 luma (4 modes, PR #13) — V/H/DC/Plane
Intra_8x8 chroma (4 modes, PR #14) — DC/H/V/Plane (4:2:0)
Intra_8x8 luma (9 modes, PRs #21 + #22) — High profile,
with 1-2-1 pre-filter
3 file moves via `git mv`, ~17 function renames stripping the `_ref`
suffix. Test binaries rewired to link daedalus_core instead of
compiling the (now moved) ref files directly. No code change — pure
plumbing for substitution-arc consumers.
26 intra prediction modes total now in the public API after this PR.
Verified on hertz:
test_intra_pred_16x16: 5/5 PASS
test_intra_pred_chroma8x8: 5/5 PASS
test_intra_pred_8x8_luma: 11/11 PASS
All via public symbols (test binaries linked against daedalus_core).
Unblocks marfrit-packages substitution arc patch 0014 — wires
H264PredContext.pred4x4[], pred16x16[], pred8x8[], pred8x8l[]
through daedalus alongside the existing IDCT / deblock / qpel / DC
Hadamard substitutions.
After 0014 lands, the libavcodec.so built by marfrit-packages will
have EVERY hot-path pixel-math kernel of an H.264 8-bit 4:2:0
decode routing through daedalus — the substitution arc is feature-
complete for the campaign target (Pi 5 Firefox YouTube playback).
