CI / test (push) Has been cancelled
chore(deploy): bin/smoke.sh — post-deploy healthcheck workflow
Runs after every deploy. Six checks against pictureframe.edholm.me:
  1. Frontend reachable (302/200 expected).
  2. Mercure hub reachable (200 expected).
  3. All pictureframe-* containers Up/healthy.
  4. No CRITICAL / Fatal / 5xx in last 5 min of php/worker/nginx logs.
  5. Authenticated /api/devices round-trip via testbot.
  6. Mercure publish→subscribe round-trip via no-op PATCH.

Catches the class of bug that just bit us today: nginx caching a stale
PHP container IP after `docker compose up -d`, and a silently-dropped
composer dep crash-looping the worker. Neither shows up in unit tests
because they're infra-level.

Per the new "post-deploy smoke check" rule: if a unit test doesn't
cover a change, run this script (or an equivalent cURL) before
declaring the deploy done.

# Post-deploy smoke check. Runs against the live host and exits non-zero on
# anything obviously broken. Intentionally noisy so failures are easy to spot.
#
# Usage: bin/smoke.sh
#
# What it covers:
# 1. Frontend reachable (homepage HTTP code).
# 2. Mercure hub reachable (HEAD on /.well-known/mercure).
# 3. Container statuses on the host (none should be Restarting/Exited).
# 4. Recent CRITICAL / Fatal / 502 entries in php + worker + nginx logs.
# 5. Authenticated /api/devices round-trip via the testbot account.
# 6. Mercure publish→subscribe round-trip via a no-op PATCH.
#
# Designed to fail fast — first red check exits 1.
