Helper for claude code settings

[hadley]

i.e. create .claude/settings.json with this:

{
  "$schema": "https://json.schemastore.org/claude-code-settings.json",
  "permissions": {
    "allow": [
      "Bash(find:*)",
      "Bash(R:*)",
      "Bash(rm:*)",
      "Bash(air format:*)",
      "Edit(/**)",
    ],
    "deny": []
  }
}

Need to rbuildignore this directory, and gitignore settings.local.json

• This directory can also contain .claude/CLAUDE.md
• We might want to exclude .Renviron by default: https://docs.claude.com/en/docs/claude-code/settings#excluding-sensitive-files (we don't use it, but others do. And whatever the dotenv package uses)
• Rscript might be a better default
• We might want to include .claude/skills/testing.md, .claude/skills/documentation.md, instead of putting those topics in CLAUDE.md

I'm finding these additions to the allow permissions to be handy:

"WebFetch(domain:raw.githubusercontent.com)",
"WebFetch(domain:github.com)"

It helps with reading GitHub issues and files.
