fix: run autoSlashCommand before claudeCodeHooks to fix slash command detection

[LadderChaos]

Summary

• Reorders chat.message hooks so autoSlashCommand runs first before claudeCodeHooks

Problem

Slash commands (e.g., /preflight, /frontend-dev) return empty content because:

1. claudeCodeHooks runs first and prepends hook content to output.parts[idx].text
2. The user's message changes from "/preflight" to "[hook content]\n\n/preflight"
3. autoSlashCommand runs next and calls detectSlashCommand(text)
4. trimmed.startsWith("/") returns false because text now starts with hook content
5. Slash command is not detected, returns empty

Fix

Move autoSlashCommand to run before any hook that modifies the message content. This ensures slash commands are detected and replaced before content modification occurs.

Testing

1. Before fix: Type /preflight → empty response
2. After fix: Type /preflight → full skill content returned

Summary by cubic

Run autoSlashCommand before claudeCodeHooks so slash commands are detected correctly. Commands like /preflight now return the expected content instead of an empty response.

Thank you for this PR! However, I'm closing it for now because:\n\n1. Merge conflicts: The PR has conflicts with the current dev branch.\n2. Not stale: The fix is still relevant and correct - this bug has NOT been fixed yet in dev.\n\nThe issue you identified is real and valid: slash commands are broken because runs before , prepending content that breaks the '/' detection.\n\nRecommendation: Please rebase this PR on the latest dev branch and resolve the conflicts, then we can review and merge it. This is a valuable bug fix that we want to incorporate.\n\nFeel free to reopen once the conflicts are resolved!
