[FEATURE] Clarify blocking vs non-blocking hook status in hook messages

Feature Description

Hook output messages should clearly indicate whether they are blocking or non-blocking. Currently, users cannot easily distinguish between informational hooks and hooks that are actually blocking their operation.

Current Behavior

Hook messages display uniformly, e.g.:

PreToolUse:Write hook success: Success
PreToolUse:Bash hook success: Success

There's no visual distinction between blocking and non-blocking hooks.

Proposed Solution

Add visual indicators to distinguish hook types:

Blocking hooks:

• 🔒 PreToolUse:Write or PreToolUse:Write (Blocking)

Non-blocking hooks:

• ℹ️ PreToolUse:Bash or PreToolUse:Bash (Non-Blocking)

Why This Matters

When multiple hooks fire, users need to quickly understand:

1. Which hooks are purely informational
2. Which hooks could block their operation
3. Why an operation might be waiting/stalled

This is especially important for users who configure custom hooks and need to debug hook behavior.
