[FEATURE] Highlighted Scripting

### Preflight Checklist

- [x] I have searched [existing requests](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20label%3Aenhancement) and this feature hasn't been requested yet
- [x] This is a single feature request (not multiple features)

### Problem Statement

If someone is trying to be careful about what scripts they are allowing Claude to write and run, normally Claude puts up a dialog box with the script text. They can be quite involved. The important things will almost always be where they are writing (often a scratch space), that they are writing, and perhaps some other triggers like checks for code insertion. I would highlight these in blue or green to make them pop out.

### Proposed Solution

Highlight file write targets and any specific inserts (as opposed to programmatic ones) to safeguard against malicious code insertion. highlight in blue perhaps.

### Alternative Solutions

_No response_

### Priority

Critical - Blocking my work

### Feature Category

CLI commands and flags

### Use Case Example

_No response_

### Additional Context

_No response_

No files or tests are named. Start by locating the CLI approval dialog that displays scripts, then trace how file-write targets and explicit insert operations are represented for rendering. Done means those elements are visually highlighted without obscuring other script content, with coverage for the relevant display behavior.
