Introduces resolveInstrumentation() in apps/web-next/src/server/bind-production.ts: reads WEB_NEXT_SENTRY_DSN; if set, calls bindSentryInstrumentation; else Noop. Both bindAllProduction and bindAllDevSeed call resolveInstrumentation() at the top. Exports __resetBindStateForTests() and __getInstrumentationForTests() for test helpers. Adds inversify + reflect-metadata as direct dependencies of web-next. Existing 6 tests still pass. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
