ci: run deploy + smoke jobs on the self-hosted peptide-vps runner (#21)

Shared pipeline deploy-staging + deploy-production (deploy-app.yml) and the Playwright staging smoke (smoke.yml) now run on the org self-hosted runner [self-hosted, peptide-vps] from the VPS stable IP, fixing the Hostinger rotating-runner-IP throttle. CI/validate stay GitHub-hosted. v1.7.1.

QA: APPROVE-WITH-P2-NOTES (2026-06-17-e6f6b67); P2 = pre-existing stale peptiderepo/ owner refs (work via redirect, ref-cleanup batch).

 # Changelog
 
+## [1.7.1] - 2026-06-17
+
+### Changed
+- **CI/CD**: Switch `deploy-staging`, `deploy-production`, and `smoke` jobs from
+  `ubuntu-latest` (GitHub-hosted) to `[self-hosted, peptide-vps]` (org runner on
+  KVM8 VPS). This routes all Hostinger SSH/rsync traffic through our stable VPS IP,
+  fixing the Azure-region throttle that caused intermittent deploy failures.
+  Callers' CI/validate jobs are unaffected (remain on `ubuntu-latest`).
