[FEATURE] reload conversation history (custom compact commands)

Problem Statement

the buildin compact command is often not serving my needs well (slow, not tailored to my workflows) so i implemented custom compact commands that manipulate session history. However to apply the new history i need to close claude code and restart it (with the correct sessionId) so chat history gets reloaded.

I would need a way to message claude-code (from hooks) that i want to reread session history.

Proposed Solution

allow returning "reload_history: true" from Stop and SubagentStop hooks, when received claude-code should reload session history
