christianandClaude Opus 5.5 ba17376132 Fix duplicate ids, validate CLI input, harden load/save
- add() uses max id + 1 so ids are never reused after rm
- done/rm reject missing, non-numeric and unknown ids; add rejects empty text
- load() gives a readable error on bad JSON or non-list data
- save() writes a temp file and renames it
- CLI checks the command before loading and no longer relies on process.exit for ls
- Add regression tests for all of the above
