feat(honcho): add role + day1 playbook + traefik route for lincoln

Deploys Honcho (plastic-labs/honcho) as a rootful Podman + Quadlet
service on the lincoln VM (10.1.71.132). Three containers on a
user-defined network:

  - honcho-postgres  pgvector/pgvector:pg16
  - honcho-api       FastAPI on :8000
  - honcho-deriver   background worker for theory-of-mind derivations

LLM provider: Anthropic Claude (claude-sonnet-4-5). Switching providers
is two env-var changes — see README.

Traefik route hall-of-presidents.local.mk-labs.cloud -> lincoln:8000
added under boilerplates/traefik/dynamic/. JARVIS itself talks to
Honcho directly at lincoln:8000 (east-west); the Traefik alias exists
only for browser access to the Swagger /docs UI.

Requires three new vault entries before first run:
  - vault_honcho_database_password
  - vault_honcho_jwt_secret
  - vault_honcho_anthropic_api_key
