Feature: Auto-name terminal sessions/tabs for easier context switching

Problem

When running multiple Claude Code sessions or background tasks, it's difficult to identify which terminal is doing what. This makes context switching painful, especially during complex workflows with parallel tasks.

Proposed Solution

Auto-generate meaningful names for terminal sessions/tabs based on context, such as:

• The task being performed (e.g., "Running tests", "Git push", "Exploring codebase")
• The working directory or project name
• The current conversation topic

This could use terminal escape sequences to set tab/window titles automatically.

Alternatives Considered

• Manually renaming tabs in the terminal emulator (tedious, doesn't scale)
• Using shell precmd hooks (doesn't capture Claude-specific context like task description)
• Using /sessions for conversation-level naming (doesn't help with terminal tab identification)

Additional Context

This would be especially useful when Claude spawns background tasks via the Bash tool with run_in_background, as those terminals have no identifying information at all.
