Subject: [PATCH] chore(release): 0.4.0

Adds `lash migrate-ids` and makes the index aware of the ID-derivation rules it
was built under, so an upgrade repairs stale unpinned task IDs on the next
`lash index` instead of serving them indefinitely.

+A task's ID is derived from its title rather than stored, so a change to the
+derivation rules moves every unpinned ID while every content hash stays
+identical — and incremental indexing, which keys off those hashes, never
+notices. This release makes the index aware of the rules it was built under,
+and adds `lash migrate-ids` to repair the `@depends-on` references a past move
+left dangling.
