luyuehm 5a82da7084 feat(routing): deterministic routing strategies for self-hosted entry (RIC-740) (#13611)
* feat(routing): self-hosted unified OpenAI-compatible entry (RIC-738)

Divert /v1/chat/completions through the self-hosted provider adapters when
OMNIROUTE_SELF_HOSTED_PROVIDERS / OMNIROUTE_SELF_HOSTED_PROVIDERS_FILE is set:
one OpenAI-compatible contract in, auto-route to the selected provider
(x-omniroute-provider header, provider/model prefix, or first provider),
standard OpenAI error shape out. Optional OMNIROUTE_SELF_HOSTED_API_KEY guards
the entry (D5 reserved); unset = open loopback route. Upstream credentials stay
runtime-only and are stripped from echoed responses.

Brings in the provider-adapters baseline from sibling branch (RIC-737) that
this entry depends on. Includes 21 passing unit tests (provider selection,
model-prefix forwarding, header hygiene, auth, error normalization, SSE
passthrough, fall-through/misconfig), docs, env example, changelog fragment.

* feat(routing): deterministic routing strategies for self-hosted entry (RIC-740)

Add the M2 deterministic routing strategy engine (D3 可审计路由) to the
self-hosted unified entry: a declarative `strategy:` block expressing five
explainable, non-predictive policies — blacklist/whitelist hard filters,
cooldown circuit breaker, cost-priority, latency-aware ordering, and an
explicit fallback chain. The ordered candidate list is the fallback chain:
a failed primary (network or non-2xx) falls through to the next candidate and
each failure feeds the breaker. Every response carries an
x-omniroute-route-decision header answering "why this model / why not that
one". A pinned provider rejected by a hard filter returns 400 (never a silent
re-route); no eligible providers returns 503 with the full explainable
decision. No ML/predict dependency.

Covers the RIC-740 acceptance: 5 strategy types with unit tests + HTTP
fault-injection tests (primary down -> fallback works), config matching docs,
and no predict/ML deps. Adds docs, .env.example entries, and a changelog
fragment.

* refactor(routing): reduce complexity-ratchet violations in new self-hosted routing files

Extract cost/id validation, pin-blocked resolution, ordering, and env/file
source resolution into small helpers so routingStrategies.ts and
selfHostedEntry.ts stay under the complexity-ratchets cap. No behavior
change — the same 51 routing-strategies/self-hosted-entry/provider-adapters
tests pass unmodified.

* docs(routing): document the 5 self-hosted env vars in ENVIRONMENT.md

check:env-doc-sync failed because OMNIROUTE_SELF_HOSTED_PROVIDERS(_FILE),
OMNIROUTE_SELF_HOSTED_API_KEY and OMNIROUTE_SELF_HOSTED_STRATEGY(_FILE)
were present in .env.example but missing from
docs/reference/ENVIRONMENT.md. Add them under "6. Tool & Routing Policies".
