Parent story: [E00-S02] Docker Compose baseline (#59)

Intent

Ensure the application does not start until PostgreSQL is healthy.

Acceptance criteria

PostgreSQL health check gates application start
app waits for the database before starting

Explicitly out of scope

compose starts DB + app (E00-S02-T01)
app health endpoint (E00-S02-T03)
DB volume persistence (E00-S02-T04)

Test plan

start the stack and confirm the app waits on database health

Rollback note

revert the healthcheck/depends_on changes

Owning stream

platform

Risk quadrant

agent-full

phase: start
objective: "[E00-S02-T02] PostgreSQL health gates app start"
plan:
  - add a healthcheck to the compose.yaml db service (pg_isready against POSTGRES_USER/POSTGRES_DB, $$-escaped so container env applies)
  - change the app service depends_on to a mapping with condition: service_healthy so the app waits for the database
  - update tests/compose-config.test.mjs to lock in both acceptance criteria (healthcheck present + healthy-gated depends_on)
  - add non-vacuous mutation probes for both criteria
  - run the committed suite, push feature/169, open PR feature/169 -> main with criterion-to-test table
out_of_scope:
  - compose starts DB + app (E00-S02-T01)
  - app health endpoint (E00-S02-T03)
  - DB volume persistence (E00-S02-T04)
