fix(status): commit unit/intent status changes to git

Unit status changes from update_unit_status() were never committed,
causing status to be lost when sessions ended. Intent completion was
only saved to ephemeral han keep storage, not to intent.md frontmatter.

Now: unit status commits happen immediately after status change,
and intent.md is updated to status: complete on intent completion.
