fix: Add find command to auto-approve bash permissions

## Problem
Getting prompted for `find` command even though we have `"Bash(find:*)"` in permissions.

## Exact Prompt
```
Bash command
find /home/linuxmint-lp/ppv/pillars/dotfiles -name ".claude" -type d | head -20
Find .claude directories in dotfiles repo

Do you want to proceed?
```

## Investigation Needed
We already have `"Bash(find:*)"` in `.claude/settings.local.json` but still getting prompted. Same issue as #605 with mkdir.

Possible causes:
- Pattern matching not working as expected
- Permissions not being loaded correctly
- Need more specific pattern

Related: #593, #600, #603, #605 (permissions work)
Principle: tracer-bullets

Start with .claude/settings.local.json and reproduce the documented find command to confirm the permission prompt. Compare its behavior with the related permission issues #593, #600, #603, and #605, then determine whether pattern matching or permission loading is responsible. Done means the find command is auto-approved by the existing Bash(find:*) permission.
