Upgrade OpenAI Go SDK to v3.54.0

[Quim Muntal (qmuntal)]

Summary

• Upgrade github.com/openai/openai-go/v3 from v3.52.0 to v3.54.0.
• Adapt Responses function-call outputs to the SDK's optional call_id API while preserving call correlation.
• Update MCP error fixtures for the SDK's structured error representation.
• Preserve Foundry project and agent-scoped routing under the SDK's stricter Azure authentication contract.

Partially supersedes #943 by extracting its OpenAI SDK upgrade and compatibility fixes. #943 still contains the remaining dependency updates.

Testing

• go test ./provider/openaiprovider ./provider/foundryprovider -count=1
• go mod tidy -diff
• git diff --check

What changed in this PR

This PR upgrades the OpenAI Go SDK (github.com/openai/openai-go/v3) to v3.54.0 and updates the OpenAI Responses and Foundry providers to remain compatible with SDK changes around function-call correlation, MCP error shapes, and Azure authentication/endpoint behavior.

Changes:

• Upgrade github.com/openai/openai-go/v3 from v3.52.0 to v3.54.0.
• Add a helper to set Responses function-call output call_id (now optional in the SDK) and update call sites to preserve tool-call correlation.
• Refactor Foundry agent client setup to satisfy the SDK’s stricter Azure endpoint/token-credential behavior while keeping Foundry routing and project/server-agent differences.

File	Description
provider/​openaiprovider/​responses.go	Adds helper for function-call output items and sets optional call_id for correlation.
provider/​openaiprovider/​responses_test.go	Updates MCP error fixtures to match the SDK’s structured error representation.
provider/​foundryprovider/​agent.go	Refactors Foundry OpenAI client setup (endpoint options + middleware) for SDK Azure contract changes.
provider/​foundryprovider/​agent_test.go	Updates Foundry request assertions (api-version omission for project mode; User-Agent check).
go.mod	Bumps OpenAI Go SDK dependency to v3.54.0.
go.sum	Updates checksums (including new transitive deps).

Scope: internal-only
Changed Go contract: None — no exported types, functions, methods, fields, or options were added, removed, or modified
Upstream evidence reviewed: No equivalent found; this PR is a Go-specific dependency upgrade (OpenAI Go SDK v3.52.0 → v3.54.0) with no analogous change required in the .NET or Python implementations
Result: out of scope

This PR upgrades github.com/openai/openai-go/v3 and adapts private provider internals (responses.go, agent.go) to the new SDK contract. All changed symbols are unexported. No public Go API surface changed, and no parity comparison is needed. The parity-approved label is correct as-is.
