refactor(render+cli): simplify verify internals (code-review follow-up)

Behavior-preserving cleanups from the code-simplifier pass, all green:
- render/src/verify.ts: `parse` arrow → function declaration (matches the other
  module-level helpers); drop a redundant `as Token[]` double-cast on section subtokens.
- cli/src/commands/verify.ts: nested ternary → if/else chain for requiredSlots.
