fix(javascript): preserve path reasons, module coverage, and property provenance (#5651)

* fix(javascript): preserve selected path host resolution reasons

Classify ELOOP and ENAMETOOLONG while resolving the caller-selected input so the path and host code stay on the invalid-request issue.

Refs #5623

* fix(javascript): count summary coverage in module units

Use the module population for both examined and total counts. Non-module graph nodes remain in the application coverage section.

* fix(javascript): connect direct property reads to return and argument flow

Record the unwrapped value expression and alias the object projection's read occurrence so a direct member read stays in backward provenance.

* fix(javascript): count return wrappers against expression depth

Evaluate the original return expression so erased TypeScript and Flow wrappers stay inside the expression-depth budget. Keep the unwrapped node for identity and value ranges.

* fix(javascript): describe ELOOP as unresolved symlink traversal

A host can return ELOOP for a cycle or for a chain past its traversal limit. Keep the selected path and code without asserting that a cycle exists.

* test(javascript): skip symlink traversal fixtures on Windows

Keep the overlong-name case portable. Windows does not produce ELOOP for these fixtures, matching the other path-failure tests.

* fix(javascript): describe ENAMETOOLONG as a path or component limit

realpath reports that code for a long component and for a long full path. Keep the selected path and host code without claiming only a filename was too long.

* style(javascript): format return-depth and object-read changes

oxfmt rejected the return-depth test and the object-read index. No behavior change.

* test(ida): expect unchanged invalid requests to be nonretryable

The shared projector no longer marks invalid_request retryable. This lookup assertion was not updated with that contract.
