feat(native-chat): show the workspace name on each reconnect row

A row read `codex · folder:8f3a1c22-… · 8 hours ago`. Recognising which chats
would reconnect is the entire point of the list, and at twenty rows a UUID
identifies nothing.

No RPC or host change was needed: the renderer can already resolve this id.
Resolved the way automation dispatch resolves the same id space
(resolveAutomationDispatchWorkspace) -- a folder workspace by its full
`folder:<uuid>` key via getKnownWorktreeById, a git worktree by its bare
`repoId::path` id via allWorktrees. Both return a Worktree, whose displayName is
a required field, and DetectedWorktree extends Worktree so either shape answers.

Falls back to the id when nothing resolves, which is what the row showed before
and also covers the window before the worktree store has hydrated.

The lookup lives in a per-row subcomponent because a hook cannot run inside
`map`, and its selector returns a primitive string so repeated selector runs
cannot churn referential equality.
