* chore: rebrand user-facing copy to OpenClaude

Replace lingering Claude Code branding in CLI, tips, and runtime UI with OpenClaude/openclaude, including the startup tip Gitlawb mention.

* chore: address branding-sweep review feedback

- PermissionRequest.tsx: rebrand the two remaining "Claude needs your
  approval/permission" notifications to OpenClaude (review-artifact and
  generic tool permission paths).
- main.tsx, teleport.tsx, session.tsx, WebFetchTool/utils.ts,
  skills/bundled/{debug,updateConfig}.ts: replace leftover `claude --…`
  CLI hints and "Claude Code" labels missed by the original sweep.
- main.tsx: drop the inline gitlawb.com marketing copy from the
  stale-prompt tip; keep it a pure rebrand.
- auth.ts: finish the half-rename so both `claude setup-token` and
  `claude auth login` references in the same error block now read
  `openclaude …`.
- mcp/client.ts: keep `name: 'claude-code'` for MCP server allowlist
  compatibility (now explicit via comment) and replace the
  "Anthropic's agentic coding tool" description with an OpenClaude one.
- MCPSettings.tsx: point the empty-server-list hint at
  https://github.com/Gitlawb/openclaude instead of code.claude.com.
