PR Output: add --dump / -T CLI flag for effective config output

# dump a real config with conditions
  cargo run --quiet --bin praxis -- -T -c examples/configs/pipeline/conditional-filters.yaml 2>/dev/null

# Output

config_source: examples/configs/pipeline/conditional-filters.yaml

PR Validation Output: Add --validate / -t CLI flag for config checking

• Add --validate / -t flag that loads and fully validates configuration then exits without starting the proxy
• Validation runs the same pipeline resolution as server startup (filter instantiation, chain expansion, ordering checks, body limits)
• Normal server startup unchanged when flag is absent

# Validate the built-in default config (should exit 0, no output)
cargo run -p praxis -- -t

MCP Queries

  GPU deep dives:
  - "What is the GPU temperature and power draw right now?"
  - "Show me tensor core activity and memory bandwidth utilization on the GPU"
  - "What are the SM and memory clock speeds — is the GPU throttling?"
  - "How much VRAM is used vs free on each GPU?"
  - "Show me PCIe throughput on the GPU node"

Failed attempts at HTTPRoute Host Header Filter Removal

Background

The ExternalModel reconciler creates an HTTPRoute with a RequestHeaderModifier filter that sets Host: <provider-endpoint> (e.g., Host: api.openai.com). This filter was questioned during PR #709 review — could BBR handle this instead, since BBR already handles path rewriting and API key injection?

We investigated whether the filter could be moved into BBR's ext-proc pipeline so that all request mutations happen in a single place.

ExternalModel Deployment & Validation Guide

Prerequisites

• OpenShift cluster with oc/kubectl access as cluster-admin
• MaaS repo cloned (e.g., ~/istio-gw/prs/4-rconciler-namespace-path/models-as-a-service)

Step 1: Deploy MaaS with ODH Operator
