This PR is a documentation only one which:
- addresses the #7231 by adding a paragraph in `docs/getting-started.md`
in the tips category to encourage users to load everything needed in
their environment
- corrects link referencing in `docs/platform-sandboxing.md` so that the
page link opens at the right section
- removes the explicit heading IDs like {#my-id} in `docs/advanced.md`
which are not supported by GitHub and are **not** rendered in the UI:

src="https://github.com/user-attachments/assets/308d33c3-81d3-4785-a6c1-e9377e6d3ea6"
/>
This caused the following links in `README.md` to not work in `main` but
to work in this branch (you can test by going to
https://github.com/openai/codex/blob/docs/getting-started-enhancement/README.md)
- the MCP link goes straight to the correct section now:
```markdown
- [**Advanced**](./docs/advanced.md)
- [Tracing / verbose logging](./docs/advanced.md#tracing--verbose-logging)
- [Model Context Protocol (MCP)](./docs/advanced.md#model-context-protocol-mcp)
```
