- attedit.rs: AtteditCommand picks an INSERT entity then iterates through
each attribute tag prompting for a new value (Enter keeps existing)
- attedit_pending_handle() / attedit_set_attrs() trait methods inject
attribute data into the command after entity-pick (avoids document access
in the command itself)
- cmd_result.rs: NeedPoint handler injects attr data; ReplaceEntity detects
the __ATTEDIT__ sentinel and calls apply_attedit() on the document
- apply_attedit() encodes tag/value pairs as __ATTEDIT__tag\x01val\x02...
- ROADMAP.md: ATTEDIT marked ✅
