Initial commit: PFI fleet inventory, stacks, tooling, and backup pipeline

Captures the full workspace state built up to this point:

  - CLAUDE.md + README.md describing conventions and the four-host fleet
    (ana-ml2, ana-docker, nh3-docker, esh-docker-vm).
  - Per-host notes under servers/<host>/ with ssh-target fallback files
    and latest system-details snapshots (two in-compose credential leaks
    scrubbed; the upstream compose files still need to move those to .env).
  - scripts/: server_inspect.sh (read-only remote diagnostic),
    refresh-server-info.sh (dir-driven discovery + snapshot capture with
    validation warnings), add-host.sh, sync-stacks.sh (pull
    compose/conf trees), deploy-stack.sh (push with per-file diff + prompt).
  - stacks/: canonical compose for backrest, beszel, dozzle, llama-swap,
    rest-server-ana, rest-server-nh3, vllm-qwen3, plus the retired
    infinity reference. All use the .env-driven + traefik-net + homepage
    label pattern.
  - configs/restic/ana-docker/: first resticprofile config + pre-backup
    hook (Synapse pg_dump, Seafile mysqldump, Vaultwarden SQLite); templates
    for the other three hosts to come.
  - docs/pfi/: general infrastructure reference carried over.
  - .gitignore excludes .env, stacks-mirror/, and assorted secret/state
    filenames to prevent re-leaks on later commits.

+# llama-swap — GGUF model server with on-demand model swapping.
+#
+# Proxies OpenAI-compatible API requests to llama.cpp server instances
+# and swaps which model is loaded into VRAM per request. Runs on
+# ana-ml2 using both GPUs dynamically (no explicit device pinning —
+# llama-swap picks per-model-definition).
+#
+# Model definitions live in /opt/docker/conf/llama-swap/config.yaml on
+# the server. Canonical copy of that config is config.yaml in this
+# workspace; deploy with scp + `docker compose restart` or the script
+# at the bottom of README.md.
+#
+# All tunables live in .env — edit that, not this file.
