Rename commands to singular (connection, scope, project) #5
Description
Summary
Rename plural command names to singular to match CLI conventions (\gh repo, \docker container, \�z group). Each command operates on a single resource, so plural naming is misleading.
Changes
- \configure connections\ -> \configure connection\
- \configure scopes\ -> \configure scope\
- \configure projects\ -> \configure project\
- Update all help text, examples, and AGENTS.md references
- Add hidden aliases for old names (one release deprecation period)
Acceptance Criteria
- All commands use singular names
- Old plural names still work but are hidden from help
- AGENTS.md updated with new command names
- \gh devlake configure --help\ shows singular names
