Adds integration contracts for MCP lifecycle, protocol errors and OAuth
configuration, A2A wire versions, the OpenAI consumer path, persisted
toolsets, callback delivery, guardrail effects, configured prices, the
filtered spend ledger, and a CircleCI-owned browser flow for project

Consolidates the eleven commits previously stacked on
litellm_integration_providers onto its rebased tip
Since #40994 the proxy relays the upstream error body on a 400, so the
public error type is now whatever the upstream sent instead of the
status-derived name. The fake upstream answered every scripted failure
with type api_error, which made the public-error contract in
test_retry_counts_and_public_errors_match_actual_provider_attempts fail
on main. The fake now sends the type a real OpenAI-compatible upstream
sends for the status, so the assertion holds whether the proxy relays
or maps the type
Adds owned local TCP peers, a Redis process helper and SigV4 helpers to
tests/integration, and integration contracts for Anthropic and Bedrock wire
shapes, Bedrock role configuration, S3 wire, observed routing, Redis
recovery and stream contracts. Consolidates the four commits previously
stacked on litellm_integration_accounting onto its main-merged tip
