C1: SHA-pin tooling dependencies (2026-04 cycle) (#344 )

## Summary

Monthly tooling dependency refresh, with a one-time conversion from version-tag pins (`rev = "vX.Y.Z"`, `image:tag`, `>=`) to SHA / digest pins everywhere.

## Changes

- **prek hooks**: all `rev = "vX.Y.Z"` → commit SHA + `# vX.Y.Z` comment. Bumped trufflehog (3.94.0→3.95.2), kingfisher (1.91.0→1.97.0), ruff (0.15.7→0.15.12), shfmt (3.13.0→3.13.1), prettier (3.8.1→3.8.3), actionlint (1.7.11→1.7.12).
- **fly/Dockerfile**: tag pins → `image@sha256:...` digest pins. Bumped nginx (1.29.6→1.30.0-alpine), tailscale (v1.94.1→v1.94.2 — still inside the safe pre-1.96.5 range), alloy (v1.14.1→v1.16.0).
- **mise-tasks**: PEP 723 inline deps converted from `>=` to `==` (PEP 508 doesn't support hashes inline). All scripts pinned to current latest: rich 15.0.0, typer 0.25.0, pyyaml 6.0.3, httpx 0.28.1.
- **prek `additional_dependencies`**: ansible-lint==26.4.0, ansible-core==2.20.5.
- **taplo-lint**: pass `--no-schema`. Upstream's `--default-schema-catalogs` returns a format taplo v0.9.3 can't parse — we don't validate against TOML schemas anyway, so this turns off the broken catalog fetch.
- **docs/update-tooling-dependencies**: documents the SHA-pin convention, `docker buildx imagetools inspect` for digest lookup, and `prek clean` before re-verifying (cache grows to several GiB).

Forgejo workflow `actions/checkout@v6.0.2` was already at the latest SHA — no change.

## Test plan

- [x] `prek run --all-files` passes after `prek clean`
- [x] `deploy-fly` workflow builds and deploys the new fly image on merge
- [x] `fly status -a blumeops-proxy` healthy after deploy
- [x] Spot-check a few mise tasks (`mise run blumeops-tasks`, `mise run docs-check-links`) to confirm pinned deps resolve cleanly

Manage Fly.io Proxy

Operational tasks for the flyio-proxy public reverse proxy.

Deploy Changes

After modifying files in fly/:

mise run fly-deploy

Pushes to fly/ on main also trigger automatic deployment via the Forgejo CI workflow.

Add a New Public Service

See expose-service-publicly#Per-service setup for the full walkthrough. In short:

Add a server block to fly/nginx.conf
Add a Fly.io certificate: fly certs add <domain> -a blumeops-proxy
Deploy: mise run fly-deploy
Verify against blumeops-proxy.fly.dev with a Host header
Add DNS CNAME via Pulumi: mise run dns-preview then mise run dns-up

Emergency Shutoff

If the proxy is causing issues (DDoS, unexpected traffic, bandwidth consumption on the home network):

Level 1 — Stop the container (seconds, reversible):

mise run fly-shutoff
# or: fly scale count 0 -a blumeops-proxy --yes

All public services go offline immediately. Tailscale tunnel drops. Zero traffic reaches indri. Restore with fly scale count 1 -a blumeops-proxy.

Level 2 — Revoke Tailscale access (seconds): Remove the flyio-proxy node in the Tailscale admin console. Even if the container is running, it cannot reach the tailnet. Use this if the container itself may be compromised.

Level 3 — Remove DNS (minutes to hours): Delete the CNAME records at Gandi. Takes time for DNS propagation but is the permanent shutoff.

Level 1 is the primary response. It is a single command, takes effect in seconds, and is trivially reversible. Keep mise run fly-shutoff somewhere easily accessible (e.g., pinned in a notes app) so it can be run quickly under stress.

Check Status

# App and machine status
fly status -a blumeops-proxy

# Live logs
fly logs -a blumeops-proxy

# Health check
curl -sf https://blumeops-proxy.fly.dev/healthz

# Certificate status
fly certs list -a blumeops-proxy

Rotate Tailscale Auth Key

The auth key expires every 90 days. To rotate:

Re-apply Pulumi to generate a new key: mise run tailnet-up
Re-run setup to stage the new secret: mise run fly-setup
Deploy to pick up the new secret: mise run fly-deploy

Rotate Fly.io API Token

See rotate-fly-deploy-token for the full rotation procedure (75-day cadence, org-scoped).

Troubleshooting

502 Bad Gateway on fresh deploy: MagicDNS may not be ready when nginx starts. The start.sh script polls nslookup before launching nginx, but if it still fails, check that tailscale status is healthy inside the container.

Health check failing: fly ssh console -a blumeops-proxy then curl localhost:8080/healthz to test locally.

TLS errors on custom domain: Check cert status with fly certs show <domain> -a blumeops-proxy. Certs auto-provision via Let's Encrypt and may take a few minutes.

High latency (>1s p50): Check if direct WireGuard peering is established: fly ssh console -a blumeops-proxy -C "tailscale ping indri". If it shows via DERP, the tunnel is relayed and latency will be 10-30s. See tailscale#Direct Peering vs DERP Relay for diagnosis.
