sci-ml/lemonade: add webui USE flag for the bundled web frontend

lemond serves a React single-page app at the server root (/) when

resources/web-app/ is present; the build passed -DBUILD_WEB_APP=OFF, so

lemond only served a static "built without a web app" placeholder there.

The new webui flag flips BUILD_WEB_APP=ON, which runs npm ci + webpack at

build time (net-libs/nodejs provides node+npm) and stages the SPA into

share/lemonade-server/resources/web-app/, where lemond auto-detects and

serves it.

The npm fetch fits the existing network build (PROPERTIES=live plus

FetchContent under RESTRICT=network-sandbox). Upstream's

USE_SYSTEM_NODEJS_MODULES path avoids the fetch but needs React, webpack

and the KaTeX assets resolvable under /usr/share/nodejs, which ::gentoo

does not package, so npm-at-build is the only viable route. Off by

default; the Tauri desktop wrapper stays unbuilt.

sci-ml/lemonade: drop stale lemonade-server hint from 10.9.0 postinst

The lemonade-server shim is no longer installed -- the build ships only
lemond and the lemonade CLI, and running lemonade-server errors. 10.10.0
already dropped this quick-start line; 10.9.0 was the last ebuild still
advertising it.

sci-ml/lemonade: fix OpenRC service failing to start

The service reported started but lemond exited immediately for two reasons
the hand-written init script never handled:

- lemond needs a writable XDG_RUNTIME_DIR (or RUNTIME_DIRECTORY) for its
control socket and refuses to start without one. supervise-daemon runs
with a clean environment that has none -- elogind's /run/user/<uid> only
exists after an interactive login, so a boot-time service cannot rely on
it. The upstream systemd unit covers this with RuntimeDirectory=lemonade;
mirror it by creating /run/lemonade (0700, owned by LEMONADE_USER) and
exporting XDG_RUNTIME_DIR.

- supervise-daemon opens the stdout/stderr redirect (LEMONADE_LOG) itself,
as the dropped user rather than as root, and dup2s it onto the child's
fds. /var/log is root-owned, so that open failed and lemond never got a
valid stdout, dying before writing a line. Pre-create the log (0640, owned
by LEMONADE_USER) in start_pre.

Both paths are overridable via LEMONADE_RUNTIME_DIR and LEMONADE_LOG in
conf.d. Revbump so installed systems pick up the corrected service scripts.

sci-ml/lemonade: reuse system ROCm to skip the TheRock download

lemond's bundled ROCm image/audio backends (sd-cpp, acestep, thinksound)
fetch AMD's multi-GB TheRock ROCm runtime into the user cache at first
use -- ~3 GB compressed, >7 GB unpacked -- which can overflow a small
/home, even though the prebuilt binaries link fine against system ROCm.

The OpenRC service now exports ROCM_PATH=/usr (Gentoo's ROCm prefix), so
lemond reuses the installed runtime and skips TheRock; documented and
overridable in conf.d. pkg_postinst now warns about the download on the
default path and points at USE=system-sdcpp (a fetch-free Vulkan route)
and the ROCM_PATH fallback. A conf.d note guards against dropping a ROCm
version file, which would make lemond gate on an exact major.minor match
against TheRock's pin and re-fetch it.

Also drops a host-specific ISA/performance claim from the reuse-block
post-install notes.

sci-ml/lemonade: drop stale lemonade-server hint from post-install notes

The C++ server ships only lemond and the lemonade CLI; the lemonade-server
shim is no longer installed, so the quick-start note pointed users at a
command that errors with "not found". Drop the line.

sci-ml/lemonade: add system-<backend> binary-reuse USE flags

Add system-<backend> USE flags (system-llamacpp, system-whispercpp,
system-sdcpp, system-kokoro): each RDEPENDs the matching portage-managed
package and jq-pins that backend + its <backend>_bin in the installed
defaults.json, so lemond reuses the system binary (llama-server,
whisper-server, sd-server, koko) instead of fetching an upstream prebuilt
into ~/.cache/lemonade/ at runtime. Pinning the backend is required because
lemond's "auto" resolves per-backend and only reads the resolved backend's
*_bin; the pinned value is just lemond's routing to the binary, not a GPU
selector.

The deps carry no backend USE constraint -- which ggml backend actually
runs is the binary's own choice (gpu_device 0 = first-registered), so a
multi-backend build picks ROCm/CUDA over Vulkan. pkg_postinst documents this
and recommends building the package vulkan-only, since Vulkan out-runs
ROCm/OpenCL on the Ryzen AI iGPU and OpenCL additionally aborts sd-server on
its XRT ICD. A has() guard fails the build if a future lemonade renames a
defaults.json section rather than silently mis-pinning.

sci-ml/lemonade: add OpenRC service, gate systemd units by USE

Upstream's CMake unconditionally installs systemd units (system + user)
that run as User=lemonade, an account nothing provided, and ships no
OpenRC integration at all.

Add IUSE="openrc systemd". Under USE=systemd keep the vendor units;
otherwise strip them and the systemd migration helper so non-systemd
installs do not carry dead files. Add acct-user/acct-group/lemonade
(unconditionally, matching sci-ml/ollama) to back the system unit's
User=lemonade.

Add an OpenRC init.d/conf.d pair modelled on the sibling llama-swap and
fastflowlm services: a supervise-daemon service that refuses to start
until LEMONADE_USER is set and passes --host 127.0.0.1, which overrides
config.json and forces a loopback bind. Reaching other interfaces now
takes a deliberate conf.d edit.

lemond already defaults to a loopback bind, so this changes packaging
and init-system coverage, not the default network exposure.

sci-ml/lemonade: pin cpp-httplib fetch to v0.38.0 for CMake 4

When ::gentoo's cpp-httplib isn't pkg-config-detectable (no .pc),
upstream FetchContents cpp-httplib at v$ (0.26.0).
That tag's CMakeLists.txt has a malformed
`if(... AND VERSION_LESS 10.0.0)` that CMake 4 rejects with "Unknown
arguments specified", breaking the build. Pin the fetch to v0.38.0 —
the version we ship as dev-cpp/cpp-httplib, API-compatible with the
>=0.26.0 floor. 10.7.0 already carries this; backport to the retained
10.6.0 and the live 9999.

In place on 10.6.0 (no revbump): build-system-only, so existing
installs are untouched — it only repairs a fresh or rollback build on
CMake 4.

sci-ml/lemonade: add 10.5.0

Routine upstream bump. CMakeLists diff against 10.4.0 is the project VERSION string
plus a Linux-irrelevant macOS-arch detection block and a flip of the upstream
BUILD_WEB_APP default (which we explicitly set OFF in src_configure regardless). All
MIN_* external-dep version pins are unchanged, so RDEPEND is untouched. Build-
verified via FEATURES=-xattr ebuild ... merge. The pre-existing VisibleVcsPkg
warning (PROPERTIES="live" + ~amd64 keywords) is inherited from 10.3.0/10.4.0 and is
a separate cleanup pass.

sci-ml/lemonade: new package, add 9999 + 10.3.0

Local AI server: optimized LLM inference on AMD NPU + GPU. C++ server
core (lemond + lemonade CLI + the deprecated lemonade-server shim)
installed under /usr to match lemond's get_resource_path() search
list — /opt prefix doesn't fit because the resolver expects
/opt/share/lemonade-server/, not /opt/lemonade/share/.

Tauri desktop wrapper and the bundled web frontend are disabled at
configure time (BUILD_TAURI_APP=OFF + BUILD_WEB_APP=OFF) for a
server-only build; both can move behind USE flags later.

PROPERTIES=live + RESTRICT=network-sandbox because cpp-httplib and
libwebsockets fall back to FetchContent under default ::gentoo
system deps (cpp-httplib lacks a .pc file; libwebsockets isn't
installed by default in this overlay). The FetchContent-built
libwebsockets.a is dropped from the install image — lemond linked
it statically already, no consumers.

USE=fastflowlm pulls in sci-ml/fastflowlm as the NPU runtime
backend; verified end-to-end (lemond + 'lemonade backends' lists
flm npu installed v0.9.39).
