Remove completed items from ROADMAP.md to keep it focused on upcoming work.

Steps

1. Read ROADMAP.md.
2. Identify all completed items — these are items whose heading line contains - [x].
3. For each completed item found:
   • The item consists of its ### - [x] heading line plus all subsequent non-heading lines (body/description) up to the next ### heading, --- separator, or ## section heading.
   • Remove the item (heading + body) from ROADMAP.md.
4. Clean up ROADMAP.md:
   • Remove any sections that are now empty (contain no ### items). Keep the section if it still has at least one ### - [ ] item.
   • Keep the header and the Success Metrics section regardless.
   • Update the *Last updated:* date at the top to today's date.
5. Show a summary of what was removed (item IDs and titles).
6. If there are no completed items to remove, say so and stop — don't make any edits.
