Subject: [PATCH] fix(analytics): only autocapture exceptions in production
 builds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The module-level posthog-node client set `enableExceptionAutocapture: true`
unconditionally. That installs a process-wide exception handler that scoops up
any exception in the process — including ones from dev/test runs. A vitest suite
that deliberately exercises a caught JSON.parse ended up surfacing as a spurious
`$exception` issue in our own error tracking (handled: true, random per-process
anonymous IDs, $lib: posthog-node).

Gate the flag on IS_PRODUCTION_BUILD so dev/CI processes no longer hijack the
exception handler. Dev/CI runs still send their normally-tagged analytics; they
just stop autocapturing unrelated throws.
