Handoff: capture install-verify gotcha + config-placement convention

Docs-only: packaging guide notes start-cli install is silent on success (verify
with installed-version/logs); AGENTS.md adds the operational-toggles-in-the-admin-
panel convention and tightens the digest Current state.

 - `$START9_BOX_HOST` resolves from your local `start-cli` context config — the real hostname is **not** in this repo.
+- **`install` prints nothing on success** (an empty log is normal, not a failure — and `${PIPESTATUS}` is a bash-ism, empty under this repo's zsh). Verify the deploy instead with:
+  ```bash
+  start-cli package installed-version ten-database   # expect the version you just built
+  start-cli package logs ten-database --limit 60     # expect server up on :8080 + a clean migration chain
+  ```
 - **Get explicit user authorization before any production deploy/install.** Verify a new migration against a **copy** of `data/crm.db` first, never the box's DB.
