delete.rs, start.rs, assign.rs all looked up the story name by reading
the content from disk/store and parsing the front matter. Replaced with
`crdt_state::read_item(&story_id).and_then(|w| w.name())`. Each callsite's
fallback chain ("CRDT → content store → filesystem") still locates the
story_id; only the name extraction moved off YAML.
