fix(backends): quote $CURDIR in run.sh so backends work in paths with spaces
The backend launcher scripts derive their own directory with
CURDIR=$(dirname "$(realpath $0)") and then referenced it unquoted as
$CURDIR (e.g. [ -f $CURDIR/lib/ld.so ], export LD_LIBRARY_PATH=$CURDIR/lib:...,
exec $CURDIR/<binary> "$@"). When a backend is installed under a path that
contains a space - notably macOS's ~/Library/Application Support/... - bash
word-splits the unquoted $CURDIR, so the test builtin fails with
"binary operator expected" and exec tries to run ".../Library/Application",
yielding "No such file or directory". The backend never starts, surfacing as
a gRPC "service not ready" error and an HTTP 500. Quote $CURDIR (and the
realpath "$0") in every affected run.sh; no logic changes.

Add a routing middleware stack and a cloud-proxy backend.
* cloud-proxy: a Go gRPC backend that forwards OpenAI- and
Anthropic-shaped chat requests to upstream providers, with an
optional translate mode (OpenAI request -> Anthropic /v1/messages
-> OpenAI response) and full tool-calling support.
* routing: admission control, content-aware model routing
(embedding cache + classifier + rerank + Arch-Router score),
PII detection/redaction (regex + NER) with streaming filter and
OpenAI/Anthropic adapters, and a per-user/per-key billing recorder
backed by GORM or in-memory storage.
* middleware: UsageMiddleware records usage via the billing recorder,
plus admission, route-model, usage-stamp and trace middlewares.
* observability: BackendTrace ring buffer stores full request bodies
(capped), MITM proxy emits structured trace events, and router
classifier decisions surface at /api/router/decide.
* gallery: Arch-Router-1.5B (Q4_K_M and Q8_0).
* UI: cloud-proxy model-editor fields, classifier system-prompt and
score-normalization config, and a Traces page rendering request
bodies.
