Bumps `third_party/llama.cpp` from `f5b7f4ad` (the #295 release pin) to `2e5fcf56a`, the tip of `1bit/hrx-vulkan-patched`.

The delta is +4 / -0 and touches 2 files only:

commit change issue
`1c0241bba` (PR#84) decline the decode-split under a non-production partial-transient alignment — `dispatch-flash-attention.cpp` `+8` engine#123 step 6 (decline-and-fall-back guarantee)
`d336ba65f` (PR#85) fold the MUL_MAT_ID WMMA f16 accumulator into f32 each 256-wide K tile — `mul_mat_id_f32_f32_wmma_core.loom` `+38/-12` engine#284 (f16 accumulator drift, +17% at K=2816)

No API change, no other submodule involved. Both fixes are gated on gfx1151 in their PRs.

Scope note: engine#300 (HRX0/Vulkan0 split >~4755 tokens) and engine#301 (ambient page migration) are not part of this bump and not part of #123 — both are path-independent of the decode-split multipass and are tracked on their own.

…tep 6) + f32 WMMA accumulator (engine#284)

Bumps third_party/llama.cpp f5b7f4ad -> 2e5fcf56a (+4/-0, 2 files: dispatch-flash-attention.cpp
and mul_mat_id_f32_f32_wmma_core.loom) and regenerates registry/architectures.json so the
recorded hrx pin matches the gitlink (registry_pins).
