Introduce `ConfigBuilder` as an alternative to our existing `Config` constructors. I noticed that the existing constructors, `Config::load_with_cli_overrides()` and `Config::load_with_cli_overrides_and_harness_overrides()`, did not take `codex_home` as a parameter, which can be a problem. Historically, when Codex was purely a CLI, we wanted to be extra sure that the creation of `codex_home` was always done via `find_codex_home()`, so we did not expose `codex_home` as a parameter when creating `Config` in business logic. But in integration tests, `codex_home` nearly always needs to be configured (as a temp directory), which is why callers would have to go through `Config::load_from_base_config_with_overrides()` instead. Now that the Codex harness also functions as an app server, which could conceivably load multiple threads where `codex_home` is parameterized differently in each one, I think it makes sense to make this configurable. Going to a builder pattern makes it more flexible to ensure an arbitrary permutation of options can be set when constructing a `Config` while using the appropriate defaults for the options that aren't set explicitly. Ultimately, I think this should make it possible for us to make `Config::load_from_base_config_with_overrides()` private because all integration tests should be able to leverage `ConfigBuilder` instead. Though there could be edge cases, so I'll pursue that migration after we get through the current config overhaul. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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 support matrix is:
macOS
Expects /usr/bin/sandbox-exec to be present.
Linux
Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: 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.
