Steve Yegge 1fbfe58ba7 Make hash IDs opt-in via id_mode config (bd-5404) ...

- Add id_mode config (sequential|hash), defaults to sequential
- Update CreateIssue/CreateIssues to check id_mode and generate appropriate IDs
- Implement lazy counter initialization from existing issues
- Update migrate --to-hash-ids to set id_mode=hash after migration
- Fix hash ID tests to set id_mode=hash
- Fix renumber test to use explicit IDs
- All 183 test packages pass

This makes hash IDs backward-compatible opt-in rather than forced default.
