ci(smoke): add comment explaining why --with-deps is omitted

OS deps are pre-installed on the self-hosted peptide-vps runner host.
--with-deps invokes apt-get which fails under the runner's NoNewPrivileges
sandbox hardening. Flag was already dropped in e00f777; this adds an
inline comment so the intent is self-documenting for future maintainers.

+### Fixed
+- **CI**: Drop `--with-deps` from `npx playwright install chromium` in `smoke.yml`.
+  The `peptide-vps` self-hosted runner has OS-level Playwright deps pre-installed by
+  root; `--with-deps` invokes `apt-get` which requires `sudo`, blocked by the runner's
+  `NoNewPrivileges=true` systemd hardening. Binary-only install works without
+  elevated privileges.## [1.7.1] - 2026-06-17
 
 ### Changed
 - **CI/CD**: Switch `deploy-staging`, `deploy-production`, and `smoke` jobs from
