Migrate devpi from minikube to indri (launchd) (#341)

## Summary

Devpi was crash-looping under memory pressure on the minikube StatefulSet, breaking the Python toolchain across the repo (`mise run docs-mikado`, `prek`, every `uv pip install`). It moves to indri as a native LaunchAgent.

## What changed

- **New ansible role** `ansible/roles/devpi/`: installs `devpi-server` + `devpi-web` into a uv-managed venv, initializes the server-dir on first run via 1Password root password, runs as a LaunchAgent (`mcquack.eblume.devpi`) bound to `127.0.0.1:3141`. Bootstraps from upstream PyPI (so devpi can install itself on a fresh box).
- **Caddy**: `pypi.ops.eblu.me` now proxies to `http://localhost:3141`.
- **Playbook**: `indri.yml` gains pre_tasks for the root password and the new role.
- **service-versions.yaml**: devpi flipped from `type: argocd` to `type: ansible`.
- **ArgoCD**: removed `apps/devpi.yaml` and `manifests/devpi/`. The in-cluster Application, namespace, and PVC have been deleted.
- **Docs**: new how-to `docs/how-to/operations/devpi-on-indri.md`; `restart-indri.md` lists devpi in the LaunchAgent stop list.

## Already deployed (live on indri)

- Service running: `launchctl list mcquack.eblume.devpi` → PID 53888
- `curl https://pypi.ops.eblu.me/+api` returns 200 ✅
- `mise run docs-mikado` works again ✅
- 1.0G of cached PyPI data was migrated from the PVC to `~erichblume/devpi/server-dir/`
- Minikube namespace and PVC fully reclaimed

## Test plan

- [ ] `mise run services-check` (after merge)
- [ ] CI workflows that use devpi succeed
- [ ] No regressions in tools that depend on `pypi.ops.eblu.me` (prek, uv-script tasks, dagger pipelines)

## Context

This is the C1 prelude to a planned C2 chain (`mikado/retire-minikube-indri`) to retire minikube on indri entirely. Doing devpi as a standalone C1 was the right call because (a) it was urgent — it was breaking the toolchain — and (b) it shakes out the migration recipe before we commit to a multi-leaf chain.

-# devpi PyPI Caching Proxy
-
-devpi-server running in Kubernetes, providing:
-- PyPI caching proxy at `root/pypi`
-- Private package hosting at `eblume/dev`
-
-## Setup
-
-### 1. Create the root password secret
-
-```fish
-kubectl create namespace devpi
-op inject -i argocd/manifests/devpi/secret-root.yaml.tpl | kubectl apply -f -
-```
-
-### 2. Deploy via ArgoCD
-
-```fish
-argocd app sync apps
-argocd app sync devpi
-```
-
-The container will auto-initialize on first startup using the root password from the secret.
-
-### 3. Create user and index (first time only)
-
-After the pod is running:
-
-```fish
-# Login to devpi as root
-uvx --from devpi-client devpi use https://pypi.tail8d86e.ts.net
-uvx --from devpi-client devpi login root
-# Enter root password when prompted
-
-# Create eblume user (prompts for password - use the one from 1Password)
-uvx --from devpi-client devpi user -c eblume email=blume.erich@gmail.com
-
-# Create private index inheriting from PyPI
-uvx --from devpi-client devpi index -c eblume/dev bases=root/pypi
-```
-
-## Usage
-
-### As pip index (caching proxy)
-
-Configure `~/.config/pip/pip.conf`:
-
-```ini
-[global]
-index-url = https://pypi.tail8d86e.ts.net/root/pypi/+simple/
-trusted-host = pypi.tail8d86e.ts.net
-```
-
-### Upload private packages
-
-```fish
-cd ~/code/personal/your-package
-uv build
-uv publish --publish-url https://pypi.tail8d86e.ts.net/eblume/dev/
-```
-
-## URLs
-
-- Web UI: https://pypi.tail8d86e.ts.net
-- PyPI cache: https://pypi.tail8d86e.ts.net/root/pypi/+simple/
-- Private index: https://pypi.tail8d86e.ts.net/eblume/dev/+simple/
-
-## Credentials
-
-Stored in 1Password vault `blumeops`, item `kyhzfifryqnuk7jeyibmmjvxxm`:
-- `root password` - devpi root user
-- `password` - eblume user password
