Craft tsconfig.build.json is now self-contained — no @sentry/typescript base

The @sentry/typescript package was removed as a dev dependency. It only provided a base tsconfig.json with strict TS settings, but dragged in deprecated tslint and vulnerable minimatch@3.1.2. All useful compiler options from its tsconfig are now inlined directly in tsconfig.build.json. Key settings carried forward: declaration, declarationMap, downlevelIteration, inlineSources, noFallthroughCasesInSwitch, noImplicitAny, noImplicitReturns, noUnusedLocals, noUnusedParameters, pretty, sourceMap, strict. The chain is: tsconfig.json extends tsconfig.build.json (no further extends).
