1.0.0-beta.22 (2026-04-17)

Added HttpClient instrumentation (AddHttpClientInstrumentation) for both tracing and metrics
in the OTLP-only telemetry path. This exports outbound HTTP client spans, enabling end-to-end
distributed trace correlation through Foundry storage and other downstream services.
Added inbound request logging middleware that logs all incoming HTTP requests with method, path,
status code, duration, correlation headers (x-request-id, x-ms-client-request-id), and
OpenTelemetry trace ID. Successful requests log at Information level; 4xx/5xx responses log at
Warning level. Request start is logged at Information level.
Added AddAgentServerLogging() and UseAgentServerLogging() extensions for Tier 3 setups to
independently enable the inbound request logging middleware.
Added startup configuration logging: platform environment, connectivity, host options, and
registered protocols are logged at Information level when the host starts.

Renamed ServerUserAgentRegistry to ServerVersionRegistry.
Renamed AgentHostBuilder.UserAgentRegistry property to VersionRegistry.
Renamed AddAgentServerUserAgent() to AddAgentServerVersion() and
UseAgentServerUserAgent() to UseAgentServerVersion(). The version middleware
no longer bundles the inbound request logging registration — use the new
AddAgentServerLogging() / UseAgentServerLogging() pair separately.
Made AgentHostTelemetry internal. The telemetry source and meter name constants
are implementation details; use the string values directly if needed for OTel filtering.
