Adds a Skillbook entry and a matching Promptbook prompt for outbound HTTP calls in Spring Boot (RestClient, WebClient, RestTemplate, HTTP interface clients).

Skill: spring-boot-http-client-guardrails

• Connect, read, pool-wait and overall timeouts with a deadline budget that fits the caller
• Explicit request factory (Boot 3.4/3.5 spring.http.client.*, Boot 4.0 spring.http.clients.*)
• Pool sizing per route, idle eviction and TTL under load balancer / Azure SNAT idle timeouts
• Idempotent-only retries in exactly one layer, circuit breaker and bulkhead per downstream
• Typed errors, body limits, OAuth2 client and SSL bundle wiring, explicit redirects, allow-listed headers
• URI-template metrics and a WireMock failure-path test matrix

Prompt: harden-spring-outbound-http-clients

• Inventory, ranked findings, fix plan, failure-path tests, and budget / pool / retry ownership tables

Catalogs are now 36 skills and 36 prompts. node scripts/site-check.mjs passes locally.
