Add dependency notice to migrate command (#995)

Current instructions would fail unless e2b was already installed

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Add `e2b` install instructions to template init/migrate outputs and
README, with minor wording tweaks and a patch changeset.
> 
> - **CLI (templates)**:
> - Update `template init` and `template migrate` post-run output to
include installing `e2b` (`npm install e2b` or `pip install e2b`).
> - Reword headings to “To get started with your template” and clarify
build command labels (run dev/prod build).
> - **Docs/Templates**:
> - Add “Installing Dependencies” section to
`packages/cli/src/templates/readme.hbs` with language-specific `e2b`
install instructions.
> - **Release**:
>   - Add patch changeset for `@e2b/cli`.
