Add js_repl host helpers and exec end events (#10672) 
## Summary

This PR adds host-integrated helper APIs for `js_repl` and updates model
guidance so the agent can use them reliably.

### What’s included

- Add `codex.tool(name, args?)` in the JS kernel so `js_repl` can call
normal Codex tools.
- Keep persistent JS state and scratch-path helpers available:
  - `codex.state`
  - `codex.tmpDir`
- Wire `js_repl` tool calls through the standard tool router path.
- Add/align `js_repl` execution completion/end event behavior with
existing tool logging patterns.
- Update dynamic prompt injection (`project_doc`) to document:
  - how to call `codex.tool(...)`
  - raw output behavior
- image flow via `view_image` (`codex.tmpDir` +
`codex.tool("view_image", ...)`)
- stdio safety guidance (`console.log` / `codex.tool`, avoid direct
`process.std*`)

## Why

- Standardize JS-side tool usage on `codex.tool(...)`
- Make `js_repl` behavior more consistent with existing tool execution
and event/logging patterns.
- Give the model enough runtime guidance to use `js_repl` safely and
effectively.

## Testing

- Added/updated unit and runtime tests for:
  - `codex.tool` calls from `js_repl` (including shell/MCP paths)
  - image handoff flow via `view_image`
  - prompt-injection text for `js_repl` guidance
  - execution/end event behavior and related regression coverage

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.
