feat(sprint-2): STYLE-005 StyleAnalyzer tests + UBA-005 UBAClient HTTP service

- STYLE-005: 19 unit tests for StyleAnalyzer (toSuggestions, analyzeProject, analyzeNode)
  - toSuggestions: ordering, message format, id format, acceptLabel variants
  - analyzeProject: repeated color/spacing detection, threshold enforcement, var() skip, tokenModel matching
  - analyzeNode: variant candidate detection, threshold, var() reference exclusion
- STYLE-005: Wire tests into test index (new tests/models/ and tests/services/ indexes)
- UBA-005: UBAClient static class with configure(), health(), openDebugStream()
  - Full auth support: bearer, api_key (custom header), basic
  - Timeout via AbortController (10s default)
  - health() never throws — always returns HealthResult
  - openDebugStream() returns DebugStreamHandle; handles named SSE event types
  - UBAClientError with status + body for non-2xx responses
