v0.1.1

0.1.1: Oracle certified live on Autonomous Database 26ai

Bump 0.1.0 -> 0.1.1. README and TESTING now record the live certification:
certify script 10/10, native VECTOR store conformance, dialect suite, and a
127-object / ~7M-row stress schema, all on Oracle AI Database 26ai. CHANGELOG
0.1.1 covers the connect-args plumbing, the OCI GenAI and local providers, the
describe-prompt everyday-words change (56% -> 92% blind), and the oci-extra
split. AnthropicProvider gains max_retries. Local ATP test harnesses stay out
of the package (.gitignore).
