* server: do not advertise a connect code without the tunnel
--connect-code on its own had no effect other than being served in
/props, so the Web UI showed a remote access code that no tunnel was
serving. Clear it when --connect is off, and say so once at startup.
The teardown comment claimed that terminate() closes the child stdout.
It does not: the log thread leaves fgets() only once every writer of
that pipe is gone, so a descendant of llama-connect would block the
join forever. Describe the real contract instead.
Also restore the --reasoning-preserve default in the generated docs.
* Update tools/connect/CMakeLists.txt

* server: dial llama-connect on the bound port and a reachable host
Pass ctx_http.port so --port 0 and the GCP override work, pick the
dial host from --host (wildcards map to loopback, IPv6 is bracketed)
and refuse --connect when only unix sockets are bound.

.pi/gg/SYSTEM.md repeated the full agent ruleset. Move it to .pi/gg/APPEND_SYSTEM.md and keep only the llama.cpp-specific rules, so it can be appended to a main system prompt with --append-system-prompt.
Drop the .pi/SYSTEM.md symlink setup from wc2wt.sh and pr2wt.sh. Worktrees no longer need it now that the folder holds an addendum instead of a full prompt.

or by a regex on the branch name, and can cancel the selected runs via --kill.

* hexagon: head-parallel flash_attn partitioning for row-split multicore
In row-split mode each core computes its output row shard of every
MUL_MAT, but flash_attn was previously partitioning by Q tokens
(flat qrow split) instead of by heads. This forced every core to
read the full KV cache (all n_kv_heads), negating the memory
bandwidth benefit of multicore on flash_attn.
Change both HMX and HVX flash_attn kernels to partition by KV heads
when n_kv_heads is divisible by n_cores: core i processes heads
[i*n_kv_heads/N, (i+1)*n_kv_heads/N) exclusively, reading only its
head shard of the KV cache. Falls back to the original token-block
split when n_kv_heads % n_cores != 0 (e.g. Gemma-4 with 2 KV heads
on 4 cores).
Controlled by GGML_HEXAGON_FA_HEAD_SPLIT (default 1 = on).
The flag is packed into bit 1 of the existing is_dst_fp32 kparams
byte to stay within the 128-byte kernel_params blob limit.
Measured gains at 4c row-split (PP t/s, ubatch=1024):
Qwen3-0.6B: 6977 -> 11026 (+58%)
llama-3.2-3B: 3717 -> 5522 (+49%)
Qwen3.5-4B: 2739 -> 2855 (+4%)
Gemma-4 MoE: no change (MoE FFN dominates, fallback path)
TG is unchanged (flash_attn is a small fraction of decode time
relative to the matmul+barrier cost per layer).

make-release-desc.sh now emits "Changelog since [vX.Y.Z](<repo>/releases/tag/vX.Y.Z)"
instead of a plain version string, so the release notes link back to the previous release.
The repo URL is derived from the origin remote (SSH or HTTPS); if it cannot be
resolved (local run without origin), the title falls back to plain text.

* ci : add API/ABI check to make-release workflow [no ci]
This commit adds an API/ABI compatibility check to the make-release
workflow.
The motivation for this to allow us to detect any potential breaking
changes in API/ABI compatibility between releases and fail the the
release if there are any.
The workflow can be triggered manually as before and this check can be
skipped if needed as it does take some time which might be useful when
doing a dry-run and not specifically interested in the API/ABI check.
By default this will check the current release against the latest
release, but this can also be configured in the workflow, or in the
script run on the command line, to check a different tag.
* add check for minor version bumps [no ci]
This commit also changes the build type to be RelWithDebInfo so that the
reported information is more useful.
