Defines the post-Plan-9 instrumentation subsystem: vendor-agnostic
Tracer/Logger interfaces in core-shared, full-depth tracing
(procedure → controller → use-case → repository) with use-case +
controller spans applied via withSpan at DI binding time and explicit
tracer.startSpan in every repository method, throw-site error capture
with __sentryReported double-report guard, and hard PII rules
(sendDefaultPii:false, default-mask replay, beforeSend/beforeSendTransaction
scrubbers, opaque user IDs only, build-time CI grep gate).
Three apps in scope (web-next, cms, web-tanstack), each with its own
Sentry project and DSN. Instrumentation binding is orthogonal to
USE_DEV_SEED/NODE_ENV repo binding. Optional dev-mode Sentry: NoopTracer
default, real SDK initializes only if DSN env is set.
