Apply the preflight to CSV purchases.

When cfg.CSVInput is set, runToolMultiService returns through runCSVPathOrFatal before reaching this check. The CSV path can then proceed to cloud calls and purchases without calling CheckAuditLogWritable, despite the all-path claim in docs/cli/purchase-safety.md Line 71. Move the check before the CSV dispatch or run it in runToolFromCSV. The CLI entry point dispatches to runToolMultiService. (raw.githubusercontent.com)

Review comment at @cmd/multi_service.go at line 125:
Move the CheckAuditLogWritable preflight in runToolMultiService before the
CSVInput dispatch so CSV purchases are verified before any cloud API calls; keep
it shared with the non-CSV path to avoid duplicate checks.

cudly verifies that the audit log is readable and writable and that the immediate configured and resolved parent directories can be opened and synced before making any cloud API calls. Higher ancestors need search permission; the immediate parent directories also need read permission and a filesystem that supports directory `fsync`. If the parent does not exist or these durability checks fail, the command exits immediately with an error.

5. Consider `--max-instances` as a final safety cap for a first run.
