Add .claude/settings.local.json to .gitignore

[TriKro]

When using Claude Code with a NanoClaw checkout, it creates .claude/settings.local.json for per-user tool permissions and MCP server config. This file is user-specific (similar to IDE workspace settings) and shouldn't be committed.

Could we add it to .gitignore? Or all of .claude?

Claude Code local settings (user-specific)

.claude/settings.local.json

This would prevent forks and downstream installations from accidentally committing local Claude Code configuration.

Thank you!

Implemented in #1734 - adds .claude/settings.local.json to the IDE section of .gitignore.
