chore: accumulated platform hardening and CI fixes

CI / Woodpecker: - Add explicit depends_on to all .woodpecker.yml steps (rdev + templates) - Fix skip_tls_verify -> skip-tls-verify (correct Kaniko flag name) - Add replicasets get/list to deployer RBAC for rollout status - Skeleton template: add failure:ignore on docs steps, Traefik TLS annotations on ingress, depends_on on verify step Component templates: - Fix container name in deploy steps (PROJECT_NAME-COMPONENT_NAME) - Replace kubectl scale with kubectl patch for replicas - Add post-deploy image verification and rollout status checks - Applied consistently across all 5 component templates Adapters: - gitea: Add HTTP client timeout (30s), context cancellation checks, handle 404 on GetRepo/DeleteRepo - zot: Add retry with exponential backoff (doWithRetry), limit response body reads to 10MB - cockroach: Use net.JoinHostPort for IPv6-safe DSN construction - woodpecker: Fix error wrapping (%v -> %w) - redis: Fix error wrapping (%v -> %w) - deployer: Add context cancellation checks Services: - apikey_service: Fix error wrapping (%v -> %w) - component_deploy: Fix error wrapping (%v -> %w) - project_infra: Fix error wrapping (%v -> %w) - webhook/dispatcher: Fix error wrapping (%v -> %w) Other: - CLAUDE.md: Add guide links for Gitea, Go 1.25, Woodpecker v3, Traefik v3, Zot registry - circuitbreaker: Add test for error wrapping - docs: Update deployment, troubleshooting, and runbook docs - health: Fix error wrapping (%v -> %w) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

+# TODO: Remove skip-tls-verify from Kaniko steps once cert verification is tested.
+#       Registry has valid LE cert via Traefik — Kaniko should be able to verify it.
+#       Test by removing from one step first. If Kaniko can't verify (runs inside
+#       cluster hitting internal service), mount the CA bundle instead.
