feat(agent): provider-agnostic single-call assistant endpoint (runs on a local model) (#1759)
WS1 rip track, RIP-2 (audit Option A), stacked on the AI provider abstraction (#1740). The first replacement for the streaming Anthropic chat runtime: a page-scoped, single-call assistant answer. - lib/agent/ask/ask-service.ts: answerAssistantQuestion() uses getAiService().generateText, so it runs on whatever backend is configured: AWS Bedrock, the direct Anthropic API, OR any OpenAI-compatible endpoint, including a local model (Qwen behind llama.cpp/Ollama/vLLM). No tool loop, no Anthropic wire format, nothing to translate per provider. The caller (a page) supplies the context; the service reads only the company's own profile for grounding, and the system prompt forbids inventing figures. - POST /api/agent/ask: same auth/rate-limit/sandbox/paywall gates as /invoke, but gated on getAiStatus().configured (not assistantAvailable), because ANY provider works here. That is the difference that lets the assistant answer on a local model where the streaming /invoke returns 503. This is the non-UI foundation of the rip: the thin /chat console and the page-scoped actions (RIP-3, UI, gated on visual sign-off) will consume this endpoint; run-turn.ts's streaming path and the intents' getAnthropic() usage are removed once nothing calls them. Verified: 10 unit tests (service prompt shape + tier + context-as-data + truncation; route 401/429/400/403 paywall/200-on-openai-compatible/503 unconfigured) + a live smoke against a local OpenAI-compatible mock (resolved provider openai-compatible, POSTed model qwen3.8 with a placeholder key, returned an answer). 421 agent/ai tests green; tsc, guards, lint clean.
