4f5e9a2fe3 test: fix test failures unrelated to exception checking
- Delete test-inspector-enabled.js: depends on process.binding("inspector")
  which is not implemented in Bun
- Skip node-options.js in test_uv_threadpool_size: depends on fixtures that
  don't exist in the napi test directory

c8d5c7a63c fix: check exception before calling specifierIsEvalEntryPoint
When moduleLoaderEvaluate finishes evaluating a module, it checks if the
module is the eval entry point to store the result. However, the condition
was checking `Bun__VM__specifierIsEvalEntryPoint(...)` before checking
`!scope.exception()`.

This caused an exception validation failure because specifierIsEvalEntryPoint
converts the JSValue key to a string (via toBunString which calls String.fromJS),
and calling fromJS while an exception is pending is invalid.

The fix swaps the order to check for exception first, leveraging short-circuit
evaluation to avoid calling specifierIsEvalEntryPoint when an exception exists.

201e3157e2 fix(cli): properly propagate exceptions from require() in --print/-e mode
When running `bun --print 'require("doesnotexist")'` or `bun -e 'require("doesnotexist")'`,
the error was being silently swallowed and `undefined` was printed with exit code 0.

The root cause was that `JSC::evaluate()` returns exceptions via an optional
`NakedPtr<Exception>` parameter rather than putting them on the throw scope.
The inline convenience version that doesn't take this parameter was being used,
which discarded the exception into an unused variable.

The fix passes a `NakedPtr<Exception>` to capture the exception and then
properly throws it onto the scope so it propagates through the module loader.

Also added exception checking in `EvalGlobalObject::moduleLoaderEvaluate` to
prevent storing results when exceptions occur in the ESM evaluation path.

Closes #25653
