docs: fix stale x-healthcheck claim, document default-user convention and healthchecks - #152

… and healthchecks
AGENTS.md claimed common.yml has a shared x-healthcheck anchor - it
never did, every service declares its own healthcheck directly.
Corrected, and added a proper "Healthchecks" section recommending
checking the image's own docs/CLI first (with cloudflared's tunnel
ready and rybbit-client's wget as real examples verified against
running containers), plus the standard shape used throughout the
catalog.
Also documents the "connect as the engine's default user, never a
scoped ${APP_NAME} user" convention in prose - previously only visible
as inline comments in each template - and notes vault env: values can
be literals as well as ${NAME} references.

Summary
common.ymlhas a sharedx-healthcheckanchor - it never did, every service declareshealthcheck:directly in its own compose file.tunnel readyand rybbit-client'swgetas real examples (both verified against running containers before being committed). Also documents the standard field shape used throughout the catalog.postgres/root/default), never a scoped${APP_NAME}user - previously only visible as inline comments in each template. Explains why (some images' "custom user" env var renames the built-in account rather than adding one; some apps hardcode which username they connect as).env:values can be literals, not just${NAME}references.depends_onguidance (item 8) which claimed "healthchecks are in common.yml" and to never usecondition:- both no longer true now thatcondition: service_healthyis used where it matters (e.g. rybbit's backend).Test plan
