[FEATURE] Add date prefix to Claude Code temp/session file names

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

Currently, Claude Code generates temp/session files in %TEMP%\claude\ (Windows)
using working directory paths as file names (e.g., d--Claude-Code--claude).
There is no way to identify when a file was created from its name alone.

Proposed Solution

Requested Feature
Add an option to prefix temp/session file names with the creation date in
YYYYMMDD format, e.g., 20260610--d--Claude-Code--claude.

Use Case

• Easier identification and manual cleanup of old session files
• Better organization when multiple sessions exist for the same project
• Helps users understand which files are safe to delete based on age

Suggested Implementation
A configurable option in settings.json, for example:
{
"tempFileNaming": "date-prefix" // default: "path-only"
}
