Feature request: Dynamic slash command reloading

Problem

Slash commands (.claude/commands/*.md) are loaded once at session start. When developing or syncing command updates across projects, users must restart Claude Code to pick up changes, losing session context.

Current workaround

• Restart Claude Code after every command change
• Use brain/context logging to manually restore session state

Proposed solution

Add a /reload command (or similar mechanism) that re-reads .claude/commands/ without requiring a full restart.

Alternatively, watch for changes to command files and reload automatically (similar to how CLAUDE.md modifications are detected mid-session).

Use case

Users maintaining shared command libraries across multiple projects (via sync scripts) need to iterate on commands without the friction of repeated restarts and context loss.
