Rename all arch references to plano (#745)
* Rename all arch references to plano across the codebase

Complete rebrand from "Arch"/"archgw" to "Plano" including:
- Config files: arch_config_schema.yaml, workflow, demo configs
- Environment variables: ARCH_CONFIG_* → PLANO_CONFIG_*
- Python CLI: variables, functions, file paths, docker mounts
- Rust crates: config paths, log messages, metadata keys
- Docker/build: Dockerfile, supervisord, .dockerignore, .gitignore
- Docker Compose: volume mounts and env vars across all demos/tests
- GitHub workflows: job/step names
- Shell scripts: log messages
- Demos: Python code, READMEs, VS Code configs, Grafana dashboard
- Docs: RST includes, code comments, config references
- Package metadata: package.json, pyproject.toml, uv.lock

External URLs (docs.archgw.com, github.com/katanemo/archgw) left as-is.

* Update remaining arch references in docs

- Rename RST cross-reference labels: arch_access_logging, arch_overview_tracing, arch_overview_threading → plano_*
- Update label references in request_lifecycle.rst
- Rename arch_config_state_storage_example.yaml → plano_config_state_storage_example.yaml
- Update config YAML comments: "Arch creates/uses" → "Plano creates/uses"
- Update "the Arch gateway" → "the Plano gateway" in configuration_reference.rst
- Update arch_config_schema.yaml reference in provider_models.py
- Rename arch_agent_router → plano_agent_router in config example

* Fix remaining arch references found in second pass

- config/docker-compose.dev.yaml: ARCH_CONFIG_FILE → PLANO_CONFIG_FILE,
  arch_config.yaml → plano_config.yaml, archgw_logs → plano_logs
- config/test_passthrough.yaml: container mount path
- tests/e2e/docker-compose.yaml: source file path (was still arch_config.yaml)
- cli/planoai/core.py: comment and log message
- crates/brightstaff/src/tracing/constants.rs: doc comment
- tests/{e2e,archgw}/common.py: get_arch_messages → get_plano_messages,
  arch_state/arch_messages variables renamed
- tests/{e2e,archgw}/test_prompt_gateway.py: updated imports and usages
- demos/shared/test_runner/{common,test_demos}.py: same renames
- tests/e2e/test_model_alias_routing.py: docstring
- .dockerignore: archgw_modelserver → plano_modelserver
- demos/use_cases/claude_code_router/pretty_model_resolution.sh: container name

Note: x-arch-* HTTP header values and Rust constant names intentionally
preserved for backwards compatibility with existing deployments.

Function calling

This demo shows how you can use Plano's core function calling capabilities.

Starting the demo

  1. Please make sure the pre-requisites are installed correctly

  2. Start Plano

  3. sh run_demo.sh
    
  4. Navigate to http://localhost:18080/

  5. You can type in queries like "how is the weather?"

Observability

Plano gateway publishes stats endpoint at http://localhost:19901/stats. In this demo we are using prometheus to pull stats from Plano and we are using grafana to visalize the stats in dashboard. To see grafana dashboard follow instructions below,

  1. Start grafana and prometheus using following command
    docker compose --profile monitoring up
    
  2. Navigate to http://localhost:3000/ to open grafana UI (use admin/grafana as credentials)
  3. From grafana left nav click on dashboards and select "Intelligent Gateway Overview" to view Plano gateway stats

Here is a sample interaction, image

Tracing

To see a tracing dashboard follow instructions below,

  1. For Jaeger, you can either use the default run_demo.sh script or run the following command:
sh run_demo.sh jaeger
  1. For Logfire, first make sure to add a LOGFIRE_API_KEY to the .env file. You can either use the default run_demo.sh script or run the following command:
sh run_demo.sh logfire
  1. For Signoz, you can either use the default run_demo.sh script or run the following command:
sh run_demo.sh signoz

If using Jaeger, navigate to http://localhost:16686/ to open Jaeger UI

If using Signoz, navigate to http://localhost:3301/ to open Signoz UI

If using Logfire, navigate to your logfire dashboard that you got the write key from to view the dashboard

Stopping Demo

  1. To end the demo, run the following command:
    sh run_demo.sh down
