feat: print row count after loading CSV (#83)#111
Merged
Conversation
Add --verbose / -v flag and automatic TTY detection so users can confirm how many rows were ingested. Prints 'Loaded <n> rows' to stderr (never stdout) after the COMMIT, with thousands separators for readability. Output is suppressed automatically in non-interactive pipelines unless --verbose is passed explicitly.
