/plans/:name, no redirect guard: the bare route is 'no plan open', which is a
real state, so the auto-select-first effect is deleted rather than turned into
a Navigate. The picker stays a native select — chrome for one document, not a
master list — but it navigates instead of setting state.
Reading the server route for this turned up a path traversal: hono
percent-decodes params, so GET /api/plans/..%2F..%2Fsecret reached
join(plansDir, '../../secret.md'). basename() the param.
