V8 Bazel Build ( #15021 )
...
Alternative approach, we use rusty_v8 for all platforms that its
predefined, but lets build from source a musl v8 version with bazel for
x86 and aarch64 only. We would need to release this on github and then
use the release.

Add feature-gated freeform js_repl core runtime ( #10674 )
...
## Summary
This PR adds an **experimental, feature-gated `js_repl` core runtime**
so models can execute JavaScript in a persistent REPL context across
tool calls.
The implementation integrates with existing feature gating, tool
registration, prompt composition, config/schema docs, and tests.
## What changed
- Added new experimental feature flag: `features.js_repl`.
- Added freeform `js_repl` tool and companion `js_repl_reset` tool.
- Gated tool availability behind `Feature::JsRepl`.
- Added conditional prompt-section injection for JS REPL instructions
via marker-based prompt processing.
- Implemented JS REPL handlers, including freeform parsing and pragma
support (timeout/reset controls).
- Added runtime resolution order for Node:
1. `CODEX_JS_REPL_NODE_PATH`
2. `js_repl_node_path` in config
3. `PATH`
- Added JS runtime assets/version files and updated docs/schema.
## Why
This enables richer agent workflows that require incremental JavaScript
execution with preserved state, while keeping rollout safe behind an
explicit feature flag.
## Testing
Coverage includes:
- Feature-flag gating behavior for tool exposure.
- Freeform parser/pragma handling edge cases.
- Runtime behavior (state persistence across calls and top-level `await`
support).
## Usage
```toml
[features]
js_repl = true
```
Optional runtime override:
- `CODEX_JS_REPL_NODE_PATH`, or
- `js_repl_node_path` in config.
