- argparse: --remote {dadeschools,prgs}, --title/--head/--base/--body,
--body-file (or '-' for stdin), and --host/--org/--repo overrides.
- REMOTES table: dadeschools (gitea.dadeschools.net/Contractor) and
prgs (gitea.prgs.cc/Scaled-Tech-Consulting).
- Print 'PR #N: <url>' on success; surface API error body on failure.
- Fix credential parsing to split('=', 1) so tokens containing '=' work.
