Goal

Base off the branch produced by the previous issue. Add three new endpoints. GET /tags returns a deduplicated sorted array of every tag string currently attached to any todo. POST /todos/:id/tags attaches a tag (from request body field tag) to the specified todo, ignoring duplicates. DELETE /todos/:id/tags/:tag removes the named tag from the specified todo if present.

Done criteria

GET /tags returns 200 with Content-Type application/json and an array (empty [] when no todos have tags)
POST /todos/:id/tags with body {"tag":"urgent"} on an existing todo returns 200 or 201 and the todo's tags array includes "urgent"
POST /todos/:id/tags called twice with the same tag does not duplicate the tag in the todo's tags array
POST /todos/:id/tags with a non-existent :id returns 404
DELETE /todos/:id/tags/:tag on an existing todo that has the tag returns 200 or 204 and subsequent GET /todos no longer includes that tag on that todo
DELETE /todos/:id/tags/:tag on a non-existent :id returns 404
After attaching tag "alpha" to two todos and "beta" to one, GET /tags returns ["alpha","beta"] (sorted, deduplicated)

Hints

Reuse the in-memory todos array from the previous issue. For GET /tags, flatMap todos to their tags then deduplicate with a Set and sort. For the delete endpoint, use Array.filter to remove the tag.
