gqa: tile-granular Ring KV (P3c) + rename to gqa_attention_* + ADR-0060/62/63/64 → Accepted

Three logically distinct changes, bundled for atomic test green:

1. **P3c — prefill_long tile-granular Ring KV** (ADR-0060 §5.5.1 amendment).
   Convert the ring from slice-granular (one full ``(d_head, S_local)``
   KV slice per step) to tile-granular (``n_tiles`` tiles of
   ``TILE_S_KV`` per step). Nested loop with outer tile, inner ring step:
   each tile propagates through all C ring positions before the next
   tile starts, so IPCQ in-flight depth stays at 1 per direction.
   Bootstrap at ``(t=0, k=0)`` outside the scratch_scope establishes the
   persistent ``(m, ℓ, O)``; every other iteration scope-wraps + persists
   via ``copy_to``. Per-rank persistent scratch shrinks to ~1 KB; per-tile
   scope bounded by TILE_S_KV regardless of S_local. Headline:
   prefill_long now completes at S_kv=128K (previously overflowed).
   New: ``tests/attention/test_gqa_prefill_long_tile_ring.py``
   (3 tests — ceiling-lift + tile-granular ipcq_copy count +
   per-CUBE distributed output regression guard).

2. **Rename ``gqa_*`` → ``gqa_attention_*``** across kernel files,
   function names, and importers. The "attention" name makes the role
   explicit (GQA is grouped-query attention) and matches upstream Triton
   FlashAttention naming conventions. Renames:
     _gqa_decode_long.py        -> _gqa_attention_decode_long.py
     _gqa_decode_short.py       -> _gqa_attention_decode_short.py
     _gqa_prefill_long.py       -> _gqa_attention_prefill_long.py
     _gqa_prefill_short.py      -> _gqa_attention_prefill_short.py
   And function names ``gqa_<phase>_<context>_kernel`` →
   ``gqa_attention_<phase>_<context>_kernel``. Updated 1 bench file
   (milestone_gqa_headline.py) and 10 test files.

3. **ADR-0060 / 0062 / 0063 / 0064: Proposed → Accepted**.
   All four are reflected in production code and covered by tests:
   - ADR-0060 (GQA fused attention): 4 kernels deployed; §5.5.1
     amendment added for the tile-granular Ring KV introduced by P3c
     (EN + KO mirror).
   - ADR-0062 (lazy tl.load): LoadFuture + _await_pending live in
     tl_context.py.
   - ADR-0063 (tl.scratch_scope + tl.copy_to): used in every chain
     reduce + tile sweep + ring step. EN-only previously; KO
     translation authored as part of this commit (CLAUDE.md
     bidirectional rule).
   - ADR-0064 (per-op-type CPU issue cost): cpu_issue_cost.py +
     issue_cost_table wiring in tl_context.py (Phase E).
   Files git mv'd from docs/adr-proposed/ to docs/adr/ (EN) and
   docs/adr-ko/ (KO). ADR-0061 (tl.broadcast) stays Proposed — no
   implementation; documented as optional convenience primitive in
   the ADR itself.

Tests: 88/88 focused regression green
(tests/attention/ + Phase E + TL discipline).
ADR pair verification: ``python tools/verify_adr_lang_pairs.py`` OK.

"""Phase 1 spec test for P3c: tile-granular Ring KV in prefill_long
(ADR-0060 §5.5 amendment + ADR-0063 §A.2).
Today's prefill_long ring sends and receives full ``(d_head, S_local)``
KV slices per step. Step 0's local-attention intermediates also live
outside any ``scratch_scope`` (they're loaded as full-slice ``Kc``,
``Vc`` and feed ``scores``, ``exp_scores`` as persistent allocations).
At larger ``S_local`` both the step-0 leak and the ring step's
in-scope intermediates grow linearly with ``S_local``, and at
``S_local = 32K`` (S_kv=128K, C=4, T_q=4) the peak overflows the
1 MiB pool.
P3c converts the ring to **tile-granular**: a nested loop
``for k in range(C): for t in range(n_tiles): ...`` where each
iteration sends/recvs one ``(d_head, TILE_S_KV)`` tile (and its V
counterpart). The persistent state shrinks to ``(m, , O)`` only
(~1 KB); per-tile in-scope scratch is bounded by
``TILE_S_KV`` regardless of ``S_local``. Ceiling lifted.
Trade-off: the per-CUBE send count grows from ``2·(C-1)`` to
``2·n_tiles·(C-1)``. At ``n_tiles=1`` (small ``S_local``) the count is
unchanged, so the existing ``test_prefill_ring_c_*`` tests at
``S_kv ∈ {16, 32}`` still pass.
Phase 1 (this commit): tests only — production code lands in Phase 2.
T1 fails today with a ``TLContext scratch overflow``; T2 fails today
with the slice-granular ipcq_copy count; T5 passes today and is a
regression guard for the per-CUBE output write count.
