Add OCI Vision MCP server

[antimverma]

Description

Adds the OCI Vision MCP server under src/oci-vision-mcp-server.

This server provides stdio MCP tools for OCI Vision image analysis and related Object Storage image workflows, including image analysis, OCR, object detection, face detection, async image jobs, Object Storage upload/list/fetch, stored result lookup, and runtime configuration status.

The implementation follows the repository MCP server structure and public packaging expectations:

• Adds pyproject.toml, uv.lock, README.md, CHANGELOG.md, LICENSE.txt, Containerfile, and oracle/ package source.
• Exposes the package entry point as oracle.oci-vision-mcp-server.
• Supports stdio transport only.
• Uses OCI CLI-compatible session-token authentication only.
• Documents that HTTP, streamable HTTP, OAuth, IDCS bearer-token validation, /mcp, and /.well-known/* endpoints are not exposed.
• Adds OCI SDK additional_user_agent telemetry derived from package metadata.
• Includes unit/integration tests with coverage threshold set to 90%.
