refactor: remove global gitattributes setup from init --stealth mode (#391)

Removes global gitattributes setup from stealth mode, keeping only the global gitignore configuration. CI failures are pre-existing (TestZFCSkipsExportAfterImport timeout).

 **Stealth mode configures:**
-- **Global gitattributes** (`~/.config/git/attributes`) - Enables beads merge for `**/.beads/issues.jsonl` files across all repos
 - **Global gitignore** (`~/.config/git/ignore`) - Ignores `**/.beads/` and `**/.claude/settings.local.json` globally
 - **Claude Code settings** (`.claude/settings.local.json`) - Adds `bd onboard` instruction for AI agents

   • Global gitignore to prevent beads files from being committed
   • Claude Code settings with bd onboard instruction
