Absorb get_slot_by_id logic into get_available_slot so slot selection
is handled by a single function call. When a specific slot id is
requested, the LCP similarity check still runs to enable proper
prompt cache updates.

* ggml-cpu: support K tails in Power10 MMA Q8/Q4 matmul
This patch removes the requirement that K be divisible by kc in the tinyBlas_Q0_PPC tiled matmul path. Process the final K panel using its actual depth and pass the reduced panel size through packing and kernel execution. This allows more workloads to use the MMA kernel and reduces fallback to mnpack.

* cuda: add GGML_OP_COL2IM_1D, follow-up to the CPU op
* cuda: col2im_1d use fast_div_modulo for the index decomposition
* cuda: col2im_1d tighten supports_op, type match and contiguous dst
* server: add "X-Accel-Buffering": "no" header to streaming endpoints
This header tells Nginx (as a reverse proxy) to NOT buffer responses. (only affects streaming endpoints)
Without it, Nginx will break streaming with certain applications (notably the Pi coding harness).
* ui : add model selector storybook stories
Covers list, favorites, single-model, all status states
(loading/loaded/sleeping/failed/idle), and selection states.
* ui : improve model selector mobile UX with hover media queries
Use @media (hover:none) to show action buttons directly on touch
devices and color-code them by model status (amber=sleeping,
green=loaded, muted=idle). Status dots hidden on touch. Desktop
hover behavior unchanged.
Throw on grammar parse failure so the server returns HTTP 400
instead of silently dropping the constraint.
Add a regression test for the invalid-grammar response.

* ggml: Conditionally enable power11 backend based on compiler support
Guard POWER11 backend creation behind a compiler flag check for -mcpu=power11. This avoids build failures on current GCC/Clang toolchains while preserving forward compatibility once POWER11 support becomes available.

ggml-cpu: Use -mcpu=power10 for P10 and P11
Reuse existing rope kernels with a function constant to toggle forward/backward
rotation, avoiding duplicate kernel code.

* metal : add f16 and bf16 support for concat operator
Extend the Metal backend concat operator to support f16 and bf16 tensor
types in addition to the existing f32 and i32 support.
- Template kernel_concat on type T with specializations for float, half,
bfloat, and int
- Add type-specific pipeline getter ggml_metal_library_get_pipeline_concat()
- Update device support check to allow f16 unconditionally and bf16 when
device supports bfloat16
- Update dispatch to select the correct kernel specialization by type

This introduces an optional feature to allocate large GPU buffers (≥ 1GB)
using USM system allocations if supported by the device. It allows using
buffers from the system allocator then letting the system manage memory
migrations between host and device as necessary.
This feature is disabled by default and requires the GGML_SYCL_USM_SYSTEM
environment variable to enable. If USM system allocations are not supported
by the device or the system, we fallback to regular allocations.
This feature can allow VRAM overcommit. For example, the test below fails
on B580 due to lack of memory for allocation, but it passes when enabling
USM system allocations:
./examples/sycl/test.sh -m Qwen3.5-27B-Q3_K_M.gguf -lv 4

* ui: add source toggle to mermaid and svg blocks
Add a toggle button next to copy and preview that switches a rendered
mermaid or svg block to its source code and back. The button is shared by
both block types and the rendered view stays the default.
The source view reuses the code block scroll container and the highlighted
code element captured at transform time, so it matches the app code blocks
without highlighting again.
Make tall diagrams scroll like text code blocks: safe centering keeps the
diagram centered when it fits and falls back to start alignment when it
overflows, so the top stays reachable instead of clipping above.
Keep the block header opaque and layered above the scrolled diagram, and
ignore header clicks in the zoom handler, so a button click never falls
through to the zoom dialog.
* ui: transparent diagram block header, address review from @allozaur
