* feat: refresh model prompt metadata

* fix: remove model-visible usage tool

* feat: migrate model prompts to markdown

* refactor: remove notebookEdit tool and rename ask to AskUserQuestion

Remove the notebookEdit tool end-to-end (impl, registration, codex
boundary, child-agent roles, write-path permissions, all 12 model
prompts, tests, docs, and harness eval scenarios). The repo has no
notebooks and the read tool has no cell-aware support to target one.

Consolidate the clarifying-question tool to a single, clearer
model-facing name:
- Drop the redundant AskUserQuestion alias that registered the same
  tool under two names.
- Rename `ask` -> `AskUserQuestion` across the registration, all 12
  model prompts (declarations + prose), harness, tests, and docs.

The internal `type: "ask"` interaction event, createAskTool factory,
and ctx.askUser plumbing are intentionally unchanged.
