fix(worker): give the worker a real health endpoint (#10987)
The image bakes in a single HEALTHCHECK that curls
http://localhost:8080/readyz, but the same image also runs `local-ai
worker`, which serves HTTP on the gRPC base port minus one and never
binds 8080. Every worker container was therefore permanently
`unhealthy` (43 consecutive failures observed on a production node),
which is worse than having no healthcheck: a genuinely broken worker and
a perfectly good one both report `unhealthy`, so the signal carries no
information and orchestration that keys on it misbehaves.
The worker already served /readyz on that port via the file-transfer
server, but as a constant 200 — it only proved the listener was bound,
which is precisely the failure mode at issue. Readiness now tracks the
live NATS connection: all of a worker's actual work (backend lifecycle
events, inference dispatch, file staging) arrives over NATS, so a worker
whose link is dead is up and useless. Registration is already implied,
since the server only starts after registration succeeds.
This reports something the controller cannot already see. The node
registry's status/last_heartbeat is fed by an HTTP heartbeat to the
frontend, a different network path from NATS — a worker can keep
heartbeating while its NATS connection is dead and still look healthy in
the registry. /healthz stays a constant 200: liveness must not follow
readiness, or a NATS blip becomes a cluster-wide restart storm.
The HEALTHCHECK is now a script that derives its endpoint from the mode
the container is actually running plus the env vars that configure the
bind address, so a frontend moved off 8080 with LOCALAI_ADDRESS (broken
the same way) and a worker on a non-default base port are both probed
correctly. Modes with no HTTP surface (agent-worker, one-shot commands)
report healthy rather than false-unhealthy. HEALTHCHECK_ENDPOINT remains
as an explicit override, so the workaround shipped in
docker-compose.distributed.yaml keeps working; both overrides in that
file are now unnecessary and have been removed.
Also fixes the latent --start-period gap. Since #10949 a frontend's
startup preload materializes HuggingFace artifacts before the HTTP
server binds (31 GB observed on a live cluster), so a healthy replica
can legitimately fail probes for a long time. --start-period is Docker's
knob for exactly this: failures inside it leave the container `starting`
instead of burning retries, and it ends early on the first success, so a
generous 60m costs a fast-starting container nothing. --timeout drops
from 10m to 10s — it is a per-probe deadline, and a localhost curl that
has not answered in 10s is itself the fault being detected.

LocalAI pulls models from OCI registries (via go-containerregistry), the
Ollama registry, and OCI blob stores (via oras), but every request went
out with the underlying library's generic User-Agent, so registry
operators had no way to attribute traffic to LocalAI.
Add an oci.UserAgent() helper that returns "LocalAI" (or
"LocalAI/<version>" when the binary is built with a version stamp via
internal.Version) and wire it into all three pull paths:
- pkg/oci/image.go: remote.WithUserAgent on the go-containerregistry
image and digest requests
- pkg/oci/ollama.go: a User-Agent header on the Ollama manifest request
- pkg/oci/blob.go: a LocalAI User-Agent on the oras blob client. This
mirrors oras' auth.DefaultClient (same retry.DefaultClient policy);
only the advertised User-Agent changes.
Implements #6258.

Add an opt-in `local-ai chat` command for testing chat models directly from the terminal without manually sending curl requests.
The command connects to a running LocalAI server, lists available models through the existing OpenAI-compatible API, streams chat completions, and supports interactive commands such as `/models`, `/model`, `/clear`, and `/exit`.
Keep `local-ai run` focused on the server lifecycle so the web UI, API clients, and multiple chat terminals can coexist against the same server.
Document the new command and terminal workflow in the README and CLI docs.
Tests:
- go test -count=1 ./core/cli/chat
- go test -count=1 ./core/cli

* docs: add 'how LocalAI works' architecture diagram
Add a blueprint-style architecture diagram: clients -> small core (API,
router, WebUI, agents) -> gRPC -> backend processes pulled on demand as
OCI images. Place it on the overview page and replace the stale external
architecture image on the reference page.

* docs: add blueprint diagrams across feature, distributed & getting-started docs
Add 24 architecture/flow/comparison diagrams (PNG + HTML source) under
docs/static/images/diagrams/, wired into their docs pages, from an
impact-vs-effort audit of the docs. Broaden the API surface on the
overview architecture diagram (OpenAI, Anthropic, ElevenLabs, Ollama,
and LocalAI's own API) and move the gRPC boundary label clear of the arrows.
Pages: distributed mode (architecture, scheduling, ds4 layer-split),
distributed inferencing, MLX, realtime, quantization, MCP, agents,
mitm & cloud proxy, middleware, reverse-proxy TLS, VRAM, voice & face
recognition, reranker, function calling, fine-tuning (recipe + jobs),
diarization, audio transform, quickstart, model resolution.

* docs: fix composable-core connectors/badge and federated-vs-worker layout
- composable-core: thicken the plug-in connectors so they read clearly, and
widen the SEPARATE IMAGE badge so its text no longer overflows the box.
- federated-vs-worker: shorten the WHOLE/SPLIT REQUEST pills to fit, and
replace the tangled node-to-node activation arrows with a clean fan-out
(request split across all sharded nodes), mirroring the federated panel.

AIO images are behind, and takes effort to maintain these. Wizard and
installation of models have been semplified massively, so AIO images
lost their purpose.
This allows us to be more laser focused on main images and reliefes
stress from CI.
