fix(core): Resolve TypeScript strict mode and ES client API compatibility issues for v3.0.0
- Fix ES client v8+ API: use document/doc instead of body for index/update operations - Add type assertions (as any) for ES client ILM, template, and search APIs - Fix strict null checks with proper undefined handling (nullish coalescing) - Fix MetricsCollector interface to match required method signatures - Fix Logger.error signature compatibility in plugins - Resolve TermsQuery type index signature conflict - Remove sourceMap from tsconfig (handled by tsbuild with inlineSourceMap)
