PR Summary

Low Risk
Low risk: small conditional change affecting only cwd initialization for JavaScript/TypeScript executions, with minimal blast radius and no security-sensitive logic.

Overview
Normalizes cwd setting for JS runtimes. change_current_directory now applies process.chdir(...) when language is javascript or typescript (instead of the legacy js value), aligning behavior across languages.

Adds a patch changeset for @e2b/code-interpreter-template documenting the normalization.

[claude]

LGTM — straightforward normalization that aligns change_current_directory with the existing language alias handling in _set_env_var_snippet.

Extended reasoning...

Overview

This PR modifies a single conditional in change_current_directory (messaging.py) to accept "javascript" and "typescript" as valid language aliases alongside the already-handled "js", and adds a changeset entry for the patch release.

Security Risks

None. The path argument is already passed unsanitized in sibling branches; this change does not alter that behavior or introduce new surface area.

Level of Scrutiny

Low. This is a one-line logic fix with no design decisions. The pattern being matched — treating "javascript" and "typescript" as equivalent aliases — is already established in _set_env_var_snippet and _delete_env_var_snippet, so this is simply bringing change_current_directory into alignment.

Other Factors

The pre-existing bug (missing del self._executions[message_id] cleanup in change_current_directory) is flagged as an inline comment but predates this PR and is out of scope here. The PR itself is correct and complete for its stated purpose.
