fix: SQL dedup by project_slug only + fish standalone flags

Address BugBot round 4 findings:

1. SQL: Changed DISTINCT to GROUP BY project_slug so the same project
   cached with slightly different names (e.g., after a rename) only
   appears once, using the most recently cached name.

2. Fish: Added flag completions for standalone commands (e.g., api
   --method). Previously only grouped subcommands had flag completions.
