* [SYCL] Fix reorder MMVQ assert on unaligned vocab sizes
The reorder mul_mat_vec_q dispatchers for Q4_0, Q8_0, Q4_K, and Q6_K
asserted that block_num_y was a multiple of 16 subgroups. Models with
a vocab size not divisible by 16 (for example HY-MT at 120818) aborted
on model load when the output projection tripped the assert.
I replaced the assert with padding: block_num_y now rounds up to a
whole number of subgroup-sized workgroups. The kernel already has the
row bounds check (`if (row >= nrows) return;`) so the extra padded
threads early-exit cleanly. Row values are uniform across a subgroup
so the collective reduce stays safe.
For aligned vocab sizes the padded block_num_y equals the old value,
so the kernel launch is identical and there is no regression.
Thanks to @arthw for flagging the relationship to #21527.
Fixes#22020.
AI assisted coding, tested on Intel B70 hardware.
* sycl: use WARP_SIZE for num_subgroups in reorder MMVQ launches
Replaces the hardcoded 16 with WARP_SIZE in the four reorder_mul_mat_vec
launch helpers (Q4_0, Q8_0, Q4_K, Q6_K). Compile-time no-op on the Intel
target where WARP_SIZE is 16, but makes the relationship to subgroup
size explicit. Per review by @NeoZhangJianyu on #22035.
Assisted by Claude.
* cache subgraph splits when cgraph is unchanged
Skip per-call subgraph construction in ggml_backend_meta_graph_compute when the same ggml_cgraph is used consecutively.
Assign uid to every sub-graph so that CUDA's fast uid check path hits too.
* Address review comments
* Keep the scope as is
* Rename last_uid and last_n_subgraphs field. Remove last_max_tmp_size field. Refactor code.
* Address review comments
* Update ggml/src/ggml-backend-meta.cpp

#21630 added the CMP0194 NEW policy to silence a CMake warning, but on Windows runners it caused CMake to prefer the MinGW toolchain for ASM and broke MSVC builds.
Reverting only that policy block restores the previous working behavior. The CMake 4.1+ warning comes back, but that is cosmetic and does not break any platform.

* server: tests: fetch random media marker via /apply-template (#21962 fix)
* server: allow pinning media marker via LLAMA_MEDIA_MARKER env var
get_media_marker() checks LLAMA_MEDIA_MARKER at first call and uses it
as-is if set, falling back to the random marker otherwise.
Tests no longer need to fetch the marker dynamically via /apply-template:
the fixture sets LLAMA_MEDIA_MARKER=<__media__> so the hardcoded prompts
work as before.
Address review feedback from ngxson
* server: make get_media_marker() thread-safe via magic statics
Use a C++11 static local with a lambda initializer instead of a global
static with an empty-check. The runtime guarantees initialization exactly
once without explicit locking.
