v0.9.30

Added

• Guided LLM configuration when none is usable (previously every review failed deep in the pipeline with "all LLM providers failed / has no api_base set"). A config counts as usable when any entry has a non-empty api_base.
  • REST: GET /api/v1/system/health now reports top-level llmConfigured; POST /api/v1/reviews and /reviews/{id}/rerun fail fast with 422 {"code": "llmNotConfigured", "error": "…"} at enqueue (after request-shape, SSRF, and credential validation — security checks keep precedence) when neither the request nor the server has a usable LLM.
  • CLI: review/ask/describe/improve/changelog now exit immediately with a guidance message listing the three configuration paths (review-engine init wizard, the resolved config file path, LLM_CONFIG env example) instead of failing mid-review.
  • Web: the Configuration page shows a warning banner (all 6 locales) when llmConfigured is false; rerunning a review that hits the 422 opens a confirm dialog offering to jump to the config page. (src/server/api/{system,review/handlers}.rs, src/cli/handlers/review.rs + all command handlers, frontend/src/views/{Configuration,ReviewHistory}.vue, frontend/src/composables/useReviews.ts, frontend/src/types/dashboard.ts)
