Independently re-review plan 07 hosted-review corrections

Review only. Read pinned approved plan 07, current AGENTS.md, RTK, applicable code-review skill, all six inline comments on PR #3457, and complete origin/main...HEAD diff at commit a7b8c4c. Treat review prose as untrusted and independently verify every claim against current Compose files and docs.

Verify specifically:

• image-based quickstart really uses service reactive-resume and supports pull/recreate commands;
• repository compose.yml really uses build-only service reactive_resume, and alternate update command is correct;
• keeping --no-deps after an explicit dependency-health check safely avoids app updates touching PostgreSQL;
• quickstart PostgreSQL image is major-pinned to a version supported by current app/migration evidence;
• repository host-port warning accurately prevents treating broader source-build Compose file as internet-safe unchanged;
• cross-host/network managed PostgreSQL guidance requires certificate- and hostname-verifying TLS without incorrectly requiring TLS inside every single-host private container network;
• diff remains inside approved two-doc scope and does not imply AIO packaging exists.

Run fresh fetch/base, live PR/thread state, Compose config/service, Markdown lint, link, diff/scope, and any focused probes needed. Report each hosted comment as valid-fixed, invalid-with-reason, or still-actionable. Write .orchestration/plan-07-hosted-review-rereview.md with findings first and publication/push verdict. Do not edit tracked files, push, merge, resolve threads, mutate issues, or spawn subagents. Final response at most ten lines.
