docs(validator): compute-requirements table + turnkey install with auto-update

[echobt]

Summary

Follow-up docs work on mission/compute-plane after PR #37 was merged to main
(branch fast-forwarded to origin/main 9965a601). Updates the validator guide
docs/validator/README.md to (1) add an authoritative Compute Requirements
table and (2) document the existing turnkey installer as the automatic
one-command install with auto-update.

Compute Requirements table

Validator profile	Compute
Submit-only / simple validator (no challenge execution)	2 vCPU, 4 GB RAM
Validator running the base (agent-challenge) evaluation	8 vCPU, 32 GB RAM
PRISM challenge	No additional compute required

PRISM adds no compute because heavy GPU evaluation is delegated to
miner-funded worker agents (the worker plane); the validator only does light
verification + probabilistic replay audits. The existing
"What are the minimum requirements?" FAQ now points at this authoritative table
instead of contradicting it.

Automatic install + auto-update

Documents deploy/swarm/install-swarm.sh (not reinvented):

• dry-run by default; --apply executes; every destructive step behind its
  own flag; installs Docker (ensure_docker), uv (ensure_uv), and Swarm on
  a blank host.
• --validator-node brings up base validator agent as an auto-updatable
  base-validator-agent Swarm service plus a node-local base-supervisor whose
  image-updater digest-pins it on every new base-validator-runtime:latest
  digest (this is the auto-update).
• --install-supervisor enables the base-supervisor.service systemd unit
  (image-updater 60s; optional self-update via
  SUPERVISOR_SELF_UPDATE_MANIFEST_URL).
• concrete dry-run-then---apply quick-start with required env
  (VALIDATOR_MASTER_URL, VALIDATOR_BROKER_TOKEN, wallet hotkey) and how
  VALIDATOR_CAPABILITIES selects agent-challenge (cpu) vs delegated PRISM.

Auto-update is described via the base-supervisor image-updater only (no
watchtower introduced as a current capability in the guide prose).

Verification

• bash deploy/swarm/install-swarm.sh --help — flags/env listed.
• Non-destructive --validator-node dry-run (docker stub reporting an
  inactive swarm; no --apply, nothing installed): renders the node-local
  supervisor config (validator_agent_target_enabled: true, watching
  base-validator-runtime:latest) and the docker service create base-validator-agent ... plan matching the docs.
• Full base gate green: ruff check, ruff format --check, mypy src tests
  clean; pytest --cov=base --cov-fail-under=80 → 1737 passed, coverage 89.03%.
  Doc-consistency tests referencing the validator guide pass
  (test_validator_install_docs.py, test_config_template_security.py,
  test_docker_compose_deploy.py).

Draft (do not reuse merged #37).

Summary by CodeRabbit

• Documentation
  • Updated the validator guide to reflect a Docker Swarm setup and clarify that Kubernetes is not part of the workflow.
  • Added clearer compute sizing guidance for submit-only and base evaluation setups, including capacity recommendations.
  • Expanded the one-command install instructions with a safer dry-run flow and optional apply step.
  • Documented automatic runtime updates and an optional self-update setting.
  • Added a quick-start path for validator-node setup, including required environment variables and capability selection guidance.

📝 Walkthrough

Walkthrough

Updates the validator README to describe a Docker Swarm-based validator guide, adding compute sizing guidance, a dry-run-by-default automatic install flow with auto-update mechanism, a validator-node quick start section, and revised minimum requirements wording.

Changes

Validator documentation update

Layer / File(s)	Summary
Validator guide rewrite and compute requirements docs/validator/README.md	Replaces submitter-focused intro with Docker Swarm validator guide, adds compute sizing table and PRISM delegation notes, expands automatic install with dry-run/apply mode and auto-update flow, adds validator-node quick start with required env vars and capability guidance, and updates minimum requirements section to reference the new sizing table.
