explanatory-output-style plugin: SessionStart hook fails due to missing execute permission on session-start.sh

Summary

The explanatory-output-style plugin ships a SessionStart hook that calls ${CLAUDE_PLUGIN_ROOT}/hooks-handlers/session-start.sh, but the script is installed without execute permissions (-rw-r--r--), causing a startup hook error on every session open.

Steps to Reproduce

1. Enable the explanatory-output-style plugin (explanatory-output-style@claude-plugins-official)
2. Open Claude Code
3. See: sessionstart: startup hook error

Root Cause

The plugin cache at:

~/.claude/plugins/cache/claude-plugins-official/explanatory-output-style/unknown/hooks-handlers/session-start.sh

is installed with permissions 644 instead of 755.

Fix

chmod +x ~/.claude/plugins/cache/claude-plugins-official/explanatory-output-style/unknown/hooks-handlers/session-start.sh

The underlying fix should ensure the script is packaged/installed with execute permissions.

Environment

• macOS Darwin 24.6.0
• Plugin version: unknown (as listed in cache directory name)
• Claude Code: latest
