feat(providers): add SAP Hyperspace (HAI) native-Anthropic provider - #34

Conversation
Adds a 'hyperspace' provider so Claude Code can route through the SAP
Hyperspace AI proxy, which exposes a native Anthropic Messages API at
/anthropic/v1 and delivers Claude, GPT, and Gemini model families through
a single approved endpoint. This lets users select a cheaper/different
model instead of the expensive org default.
Transport mirrors the OpenRouter native path (Bearer auth +
anthropic-version header, shared native SSE block policy). Wired into the
single-source provider catalog, settings (api_key/keys/base_url/proxy/
usage_limit + validators), registry factory, defaults re-export,
.env.example, and README provider docs.
Files: config/provider_catalog.py, config/settings.py, providers/defaults.py,
providers/registry.py, providers/hyperspace/{__init__,client,request}.py,
tests/providers/test_hyperspace.py, .env.example, README.md
Verification: ruff format --check + ruff check pass; full pytest suite
883 passed (5 new). ty check delta is clean — the only 2 new diagnostics
are the pre-existing environment-specific 'providers.base unresolved-import'
false positive that already affects every provider client/test locally and
passes on CI's Linux runner.

What
Adds a
hyperspaceprovider so Claude Code can route through the SAP Hyperspace AI proxy (HAI) — a native Anthropic Messages relay at/anthropic/v1that delivers Claude, GPT, and Gemini model families through one approved endpoint.Why
Lets Claude Code users pick a cheaper/different model (e.g. Gemini or GPT) instead of always paying for the most expensive default model.
