pi-neuralwatt v0.16.0

e7b6b5d: Add a provider.api setting (/neuralwatt:settings → API, default openai-completions) that serves the catalog on Neuralwatt’s Anthropic-compatible POST /v1/messages endpoint (vLLM-backed) — native tool use and thinking streams with the same model ids. Applies on /reload.
- Thinking levels resolve per model from the catalog’s supported_efforts + effort_aliases (vLLM’s output_config.effort enum only accepts native values); reasoning off is expressed as chat_template_kwargs.enable_thinking=false because the endpoint accepts but ignores thinking:{type:"disabled"}.
- Usage cost on this surface is rate-derived from the model’s per-MTok pricing (the adapter discards the server’s cost field).
- Quota tracking works on both surfaces: /v1/messages streams emit the same : energy / : cost SSE comments as chat-completions, which the stream tee now feeds into the same quota events; per-response quota headers remain chat-completions-only and /v1/quota polling is unchanged. SSE cost comments that carry an absolute allowance_remaining_usd now update the credit balance directly on both surfaces.

2117f48: fix: remove model-id aliases that should have been dropped with the provider config section

The provider no longer appends alias entries (HuggingFace-style ids such as zai-org/GLM-5.2-FP8) to the catalog; only canonical ids are registered. Aliases were unconditional leftovers from the config toggles removed earlier. Sessions pinned to an alias id must re-select the canonical model. Stale alias entries persisted in ~/.pi/agent/models-store.json age out via the existing TTL/refresh path; no store migration is needed.
