fix(#2337): capture and surface todo severity (#2381)

add-todo.md gains a confirm-based infer_severity step (infer from the blocker/major/minor/cosmetic taxonomy, confirm via AskUserQuestion with TEXT_MODE fallback, before writing) and a severity frontmatter field. cmdListTodos and cmdInitTodos now surface severity, backward-compatible (key omitted when absent), in parity.

Closes #2337. Admin-merged (self-review bypass) with full green CI.
