claude-noether 1f07f3cd70 h264: expose chroma DC 2x2 Hadamard as public API
PR #23 added the Hadamard as a test-only spec reference; this PR
promotes it to a public symbol in src/ so consumers (the eventual
marfrit-packages substitution-arc patch 0011) can link against it.

  New: void daedalus_h264_chroma_dc_hadamard_2x2(int16_t c[4]);
       — operates in-place on 4 int16, no QP-dependent scaling
       (caller composes that themselves per §8.5.11.2).

The src/ implementation is byte-for-byte identical to the test-only
ref in tests/h264_chroma_dc_hadamard_ref.c (kept as a separate
spec-validation copy).  A new "public API parity" test case verifies
the two produce identical output for a non-trivial input.

Pure CPU primitive — no substrate-dispatch wrapper because the work
is 4 adds + 4 subs; the substrate machinery would cost more than
the kernel itself.

Verified on hertz:

  $ ./build/test_chroma_dc_hadamard
    all-uniform 5                    PASS
    col gradient [0,10,0,10]         PASS
    row gradient [0,0,10,10]         PASS
    anti-diagonal [10,0,0,10]        PASS
    asymmetric [1,2,3,4]             PASS
    sign-alternating [-5,5,-5,5]     PASS
    double-Hadamard = 4*orig         PASS
    public API parity vs _ref        PASS

  ALL chroma DC Hadamard tests PASS

  $ nm -g build/libdaedalus_core.a | grep chroma_dc_hadamard
  0000000000000000 T daedalus_h264_chroma_dc_hadamard_2x2

Unblocks marfrit-packages 0011 (substituting
H264DSPContext.chroma_dc_dequant_idct, which composes the Hadamard
+ qmul scaling).

# pkg-config substitutes ${pcfiledir} with the directory holding the

# <prefix>/<libdir>/pkgconfig back to <prefix> tells pkg-config the
# install prefix without baking it in. This is why
# `cmake --install build --prefix /foo` produces a .pc that correctly
# resolves `prefix=/foo` instead of baking whatever CMAKE_INSTALL_PREFIX
# was at *configure* time (default /usr/local). DESTDIR-staged
# installs work too: at runtime pkg-config sees the .pc at its real
# install path and computes the right prefix.
#
# Relative-path depth is computed from CMAKE_INSTALL_LIBDIR (and
# whatever multiarch tuple GNUInstallDirs adds) so Debian-style
# `lib/aarch64-linux-gnu/pkgconfig/...` resolves with the right number
# of `..` components. Layouts where libdir is *not* under prefix are
# not supported by this scheme; if a packager overrides libdir to an
# absolute path the relative-path machinery falls back to the absolute
# value (CMake's file(RELATIVE_PATH) prepends `..` until they meet),
# which is also relocatable but no longer prefix-agnostic.
