feat(remote-config): expose remote config state over the agent IPC HTTP API

[louis-cqrl]

What does this PR do?

Adds a GET /agent/remote-config/state endpoint to the Agent's authenticated IPC HTTP (CMD) API that returns the Remote Config repositories state as JSON. It exposes the same data as the existing AgentSecure.GetConfigState gRPC method, registered through the standard agent_endpoint provider group from the rcservice component (so it inherits the IPC auth-token middleware). When remote config is disabled it responds 503 with a not-initialized error.

Motivation

First change in a stacked series that exposes a subset of datadog-agent CLI actions through the Datadog MCP server, using Action Platform + the co-located Private Action Runner (PAR) as the transport.

PAR reaches the Agent over the local authenticated HTTP API, the same way CLI subcommands do. status, diagnose, and config already have HTTP endpoints, but the Remote Config state was only available over gRPC — which PAR has no client for. This endpoint unblocks the getRemoteConfigState PAR action (PR 3 of the datadog-agent stack).

Describe how you validated your changes

bazel build //comp/remote-config/rcservice/impl:impl passes; pre-push go-linter and go-test hooks pass.

Additional Notes

Stacked series (merge in order). datadog-agent: (1) this PR → (2) read-only com.datadoghq.agent bundle → (3) getRemoteConfigState action → (4) mutating setConfig/generateFlare actions. Companion dd-source stack: (5) bundle manifest → (6) read-only MCP tools → (7) confirm-gated mutating MCP tools → (8) MCP OBO allow-list.

End-to-end: MCP tool call → wf-actions-server (ExecuteActionOnBehalfOf) → per-runner Courier queue → the install's co-located PAR → PAR runs the com.datadoghq.agent bundle action → the action calls the Agent's local IPC HTTP API (reusing the Agent's auth token/cert) → response flows back to the MCP tool result.

Explanation

Confidence level: 90.00%
Effect size tolerance: |Δ mean %| ≥ 5.00%

Performance changes are noted in the perf column of each table:

• ✅ = significantly better comparison variant performance
• ❌ = significantly worse comparison variant performance
• ➖ = no significant change in performance

A regression test is an A/B test of target performance in a repeatable rig, where "performance" is measured as "comparison variant minus baseline variant" for an optimization goal (e.g., ingress throughput). Due to intrinsic variability in measuring that goal, we can only estimate its mean value for each experiment; we report uncertainty in that value as a 90.00% confidence interval denoted "Δ mean % CI".

For each experiment, we decide whether a change in performance is a "regression" -- a change worth investigating further -- if all of the following criteria are true:

1. Its estimated |Δ mean %| ≥ 5.00%, indicating the change is big enough to merit a closer look.

2. Its 90.00% confidence interval "Δ mean % CI" does not contain zero, indicating that if our statistical model is accurate, there is at least a 90.00% chance there is a difference in performance between baseline and comparison variants.

3. Its configuration does not mark it "erratic".

Replicate Execution Details

We run multiple replicates for each experiment/variant. However, we allow replicates to be automatically retried if there are any failures, up to 8 times, at which point the replicate is marked dead and we are unable to run analysis for the entire experiment. We call each of these attempts at running replicates a replicate execution. This section lists all replicate executions that failed due to the target crashing or being oom killed.

Note: In the below tables we bucket failures by experiment, variant, and failure type. For each of these buckets we list out the replicate indexes that failed with an annotation signifying how many times said replicate failed with the given failure mode. In the below example the baseline variant of the experiment named experiment_with_failures had two replicates that failed by oom kills. Replicate 0, which failed 8 executions, and replicate 1 which failed 6 executions, all with the same failure mode.
