Added both, following the existing Ada style in this directory (Ada.Real_Time Clock-based timing with the "microseconds-per-iteration" Time_Span division trick already used by nstream.adb/transpose.adb, Argument_Count-based CLI parsing with defaults, same closed-form validation approach as the other ports). Running the existing kernels end-to-end surfaced two real, pre-existing bugs, not just missing coverage: - transpose.adb never actually transposed anything: its timed loop was `for I in 1..Order loop A(I,J) := A(I,J) + B(I,J); end loop` with J fixed at its declared-but-never-reassigned value of 1 -- a 1-D loop over a single column, no cross-indexing at all. It also initialized A to all zeros and validated by checking A stayed at zero, which cannot correspond to any real transpose algorithm. Confirmed by running it: it printed "Asum= 2.20000E+04" and never reached the timing output, i.e. validation always failed. Rewritten as a real B += A^T with the standard PRK closed-form checksum. - stencil (once written) failed validation for the grid pattern and larger radii, but not the default star/radius=2 case: Ada.Numerics. Real_Arrays.Real_Matrix is single-precision Float, and accumulating more terms per point (grid pattern, or larger radius) lost enough precision to exceed the 1.0E-8 tolerance. Every other language port of this kernel uses double precision. Fixed by defining a local Long_Float matrix type instead of Real_Matrix for p2p/stencil/ transpose, rather than loosening the tolerance. - Every one of p2p/stencil/transpose stack-allocates its matrices; at realistic benchmark sizes (e.g. 1000x1000 Long_Float = 8MB per array) that reliably blew the 8MB default stack (STORAGE_ERROR). Switched all three to heap allocation via an access type, the same pattern nstream_array.adb already established in this directory for exactly this reason. nstream.adb itself is left as the original small-array stack-based variant (works up to ~500K elements); nstream_array.adb remains the one to use for large vector lengths. Verified: `make` builds all 7 programs cleanly (gnatmake, no warnings on the new/changed files); ran every kernel across multiple sizes/ patterns (p2p at 1000x1000 and 4000x4000, transpose at 1000 and 2000, stencil at star/grid x radius 2/4 x multiple sizes) -- all validate, with rates in a consistent, physically sensible range for scalar Ada (p2p ~134 MFlops/s regardless of grid size, matching its inherently sequential dependency chain; transpose ~700 MB/s; stencil ~140-155 MFlops/s across all pattern/radius/size combinations).

Verified: clean build, no compiler warnings. Ran nstream at 500K (the old stack limit), 1M (previously STORAGE_ERROR), 16M, and 100M elements -- all validate with consistent ~6.6-6.8 GB/s bandwidth, no more artificial size cap. Re-ran the rest of ADA/ (p2p, transpose, stencil star/grid) to confirm nothing else regressed.

Custom targets are named ada_ (unique across the combined root project, same reasoning as every other language's CMakeLists.txt), but since these are custom targets/commands rather than real add_executable() targets, there's no OUTPUT_NAME to reconcile -- the produced binary is simply named directly and CTest invokes it by that known path. Verified: standalone `cd ADA && cmake -S . -B build && cmake --build build` builds all 4 kernels cleanly with the ADA/ source directory left untouched; all 6 CTest cases (nstream, p2p, transpose, stencil x star/grid/radius-4) pass. Also verified combined at the repo root with all other languages enabled: clean configure (no target-name collisions), full build succeeds, and the combined CTest run is 203/209 passing with the same 4 pre-existing unrelated failures as before this change (no regressions).
