chore: bump Claude Code to 2.1.83 and Agent SDK to 0.2.83

* Auto-set CLAUDE_CODE_SUBPROCESS_ENV_SCRUB when allowed_non_write_users is configured

Sets the env var automatically whenever allowed_non_write_users is
non-empty, so downstream workflows don't need to add it manually.
Updates the input description and docs/security.md to note the behavior.

🏠 Remote-Dev: homespace

* Fall back to inherited env when allowed_non_write_users is unset

🏠 Remote-Dev: homespace

* Let workflow/job env override the auto-set scrub flag

Env var takes priority so users can opt in/out via CLAUDE_CODE_SUBPROCESS_ENV_SCRUB
at job or workflow level independently of allowed_non_write_users.
