Dylan 90d892f4fd [prompt] Restore important guidance for shell command usage (#2211 )

## Summary
In #1939 we overhauled a lot of our prompt. This was largely good, but
we're seeing some specific points of confusion from the model! This
prompt update attempts to address 3 of them:
- Enforcing the use of `ripgrep`, which is bundled as a dependency when
installed with homebrew. We should do the same on node (in progress)
- Explicit guidance on reading files in chunks.
- Slight adjustment to networking sandbox language. `enabled` /
`restricted` is anecdotally less confusing to the model and requires
less reasoning to escalate for approval.

We are going to continue iterating on shell usage and tools, but this
restores us to best practices for current model snapshots.

codex-core

This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.

Dependencies

Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this

macOS

Expects /usr/bin/sandbox-exec to be present.

Linux

Expects the binary containing codex-core to run the equivalent of codex debug landlock when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.

All Platforms

Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
