To support Bazelification in https://github.com/openai/codex/pull/8875, this PR introduces a new `find_resource!` macro that we use in place of our existing logic in tests that looks for resources relative to the compile-time `CARGO_MANIFEST_DIR` env var. To make this work, we plan to add the following to all `rust_library()` and `rust_test()` Bazel rules in the project: ``` rustc_env = { "BAZEL_PACKAGE": native.package_name(), }, ``` Our new `find_resource!` macro reads this value via `option_env!("BAZEL_PACKAGE")` so that the Bazel package _of the code using `find_resource!`_ is injected into the code expanded from the macro. (If `find_resource()` were a function, then `option_env!("BAZEL_PACKAGE")` would always be `codex-rs/utils/cargo-bin`, which is not what we want.) Note we only consider the `BAZEL_PACKAGE` value when the `RUNFILES_DIR` environment variable is set at runtime, indicating that the test is being run by Bazel. In this case, we have to concatenate the runtime `RUNFILES_DIR` with the compile-time `BAZEL_PACKAGE` value to build the path to the resource. In testing this change, I discovered one funky edge case in `codex-rs/exec-server/tests/common/lib.rs` where we have to _normalize_ (but not canonicalize!) the result from `find_resource!` because the path contains a `common/..` component that does not exist on disk when the test is run under Bazel, so it must be semantically normalized using the [`path-absolutize`](https://crates.io/crates/path-absolutize) crate before it is passed to `dotslash fetch`. Because this new behavior may be non-obvious, this PR also updates `AGENTS.md` to make humans/Codex aware that this API is preferred.
