fix: remove duplicate declaration of tool.poetry.extras

[daniel-cohere]

This PR introduces new dependencies and updates the lock file to version 2.1.

• Adds new dependencies:
  • cffi for Foreign Function Interface
  • circuitbreaker for Python Circuit Breaker pattern implementation
  • cryptography for cryptographic recipes and primitives
  • oci for Oracle Cloud Infrastructure Python SDK
  • pycparser for C parser in Python
  • pyopenssl for Python wrapper around OpenSSL
  • pytz for world timezone definitions
• Updates groups and markers for several existing dependencies
• Removes [tool.poetry.extras] section and adds oci extra to [tool.poetry.extras] at the end of the file
• Updates lock-version to 2.1 in poetry.lock

---

Note

Medium Risk
Regenerating poetry.lock with a newer Poetry version and adding the oci extra changes dependency resolution/markers and can affect downstream installs, though no runtime code is modified.

Overview
Cleans up pyproject.toml by removing a duplicate [tool.poetry.extras] declaration and consolidating optional extras so aiohttp and oci are defined in a single section.

Regenerates poetry.lock with Poetry 2.0.1, bumping the lock format (2.0 → 2.1) and updating metadata/markers/groups; this also records the oci optional dependency set (e.g., oci plus cryptography/pyOpenSSL and related transitive deps).
