DottaandPaperclip baa4a2e64e fix(runner): restore Codex auth before source recovery (#18612)
Restore disposable Codex authentication and safe provider configuration before cold source recovery. Preserve source receipts and conversation state until reconciliation, and rebuild assigned tools from the admitted launch binding.

Validate remote launch destinations, clear stale authentication when no selected credential exists, and atomically publish SSH file transfers without following retained links. Red/green recovery regressions, a real two-turn Codex/MCP probe, and all current PR checks pass.
