fix(nix): use correct version from Cargo.toml in flake build (#11770 )

## Summary

- When building via `nix build`, the binary reports `codex-cli 0.0.0`
because the workspace `Cargo.toml` uses `0.0.0` as a placeholder on
`main`. This causes the update checker to always prompt users to upgrade
even when running the latest code.
- Reads the version from `codex-rs/Cargo.toml` at flake evaluation time
using `builtins.fromTOML` and patches it into the workspace `Cargo.toml`
before cargo builds via `postPatch`.
- On release commits (e.g. tag `rust-v0.101.0`), the real version is
used as-is. On `main` branch builds, falls back to
`0.0.0-dev+<shortRev>` (or `0.0.0-dev+dirty`), which the update
checker's `parse_version` ignores — suppressing the spurious upgrade
prompt.

| Scenario | Cargo.toml version | Nix `version` | Binary reports |
Upgrade nag? |
|---|---|---|---|---|
| Release commit (e.g. `rust-v0.101.0`) | `0.101.0` | `0.101.0` |
`codex-cli 0.101.0` | Only if newer exists |
| Main branch (committed) | `0.0.0` | `0.0.0-dev+b934ffc` | `codex-cli
0.0.0-dev+b934ffc` | No |
| Main branch (uncommitted) | `0.0.0` | `0.0.0-dev+dirty` | `codex-cli
0.0.0-dev+dirty` | No |

## Test plan

- [ ] `nix build` from `main` branch and verify `codex --version`
reports `0.0.0-dev+<shortRev>` instead of `0.0.0`
- [ ] Verify the update checker does not show a spurious upgrade prompt
for dev builds
- [ ] Confirm that on a release commit where `Cargo.toml` has a real
version, the binary reports that version correctly

fix(nix): update flake for newer Rust toolchain requirements (#10302 )

## Summary

- Add rust-overlay input to provide newer Rust versions (rama crates
require rustc 1.91.0+)
- Add devShells output with complete development environment
- Add missing git dependency hashes to codex-rs/default.nix

## Changes

**flake.nix:**
- Added `rust-overlay` input to get newer Rust toolchains
- Updated `packages` output to use `rust-bin.stable.latest.minimal` for
builds
- Added `devShells` output with:
  - Rust with `rust-src` and `rust-analyzer` extensions for IDE support
- Required build dependencies: `pkg-config`, `openssl`, `cmake`,
`libclang`
  - Environment variables: `PKG_CONFIG_PATH`, `LIBCLANG_PATH`

**codex-rs/default.nix:**
- Added missing `outputHashes` for git dependencies:
  - `nucleo-0.5.0`, `nucleo-matcher-0.3.1`
  - `runfiles-0.1.0`
  - `tokio-tungstenite-0.28.0`, `tungstenite-0.28.0`

## Test Plan

- [x] `nix develop` enters shell successfully
- [x] `nix develop -c rustc --version` shows 1.93.0
- [x] `nix develop -c cargo build` completes successfully

Fix nix build (#4048 )

I dropped the build of the old cli from the flake, where the default.nix
already seemed to removed in a previous iterations. Then I updated
flake.nix and codex-rs expression to be able to build again (see
individual commits for details).

Tested by running the following builds:


```
$ nix build .#packages.x86_64-linux.codex-rs
$ nix build .#packages.aarch64-darwin.codex-cli
```

restructure flake for codex-rs (#888 )

Right now since the repo is having two different implementations of
codex, flake was updated to work with both typescript implementation and
rust implementation

feat: add Nix flake for reproducible development environments (#225 )

This PR introduces a Nix flake configuration to enable reproducible
development environments:

- Adds flake.nix defining a devShell with necessary dependencies.
- Updates README.md with usage instructions for `nix develop`.
- Ensures CI compatibility with Nix for consistent builds.
