[FEATURE] Add /copy-location command to capture session + working directory for easy resuming

Preflight Checklist

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

Problem Statement

When working with Claude Code across multiple projects and directories, it's difficult to "bookmark" a specific
conversation thread for later resuming. While /rename and claude --resume work great for session management, they
don't capture the working directory context.

Current workflow:

1. cd /path/to/project
2. claude --resume my-session

If I switch terminals or directories, I need to manually remember both the directory and session name.

Proposed Solution

Add a /copy-location command that outputs (and optionally copies to clipboard) a runnable command:

> /copy-location
Copied to clipboard: cd /Users/me/project-a && claude --resume auth-refactor

Alternative Solutions

Alternative/additional syntax:
> /copy-location --format url
Copied: claude-code://resume/auth-refactor?cwd=/Users/me/project-a

Benefits

• Shareable session links for team collaboration
• Easy bookmarking in task managers or notes
• Reduces friction when context-switching across multiple projects
• Natural extension of existing /resume functionality

Workarounds (current)

Manually constructing commands like:
cd /path/to/project && claude --resume session-name

But this requires remembering both pieces of information and manually typing them out.

Priority

High - Significant impact on productivity

Use Case Example

I often have multiple Claude Code sessions running in different project directories:

• /Users/me/project-a → session "auth-refactor"
• /Users/me/project-b → session "bug-fix-123"

I'd like to paste a "location" into my notes, Slack, or task manager that I can later copy and paste back into a
terminal to resume exactly where I left off.
