Summary by cubic

Adds automatic discovery of Xcode Coding Assistant sessions on macOS for Claude Code and Codex, so usage is picked up without extra config. Updates docs and tests to reflect the new macOS defaults and the “available” status wording.

• New Features
  • Claude Code: includes ~/Library/Developer/Xcode/CodingAssistant/ClaudeAgentConfig/projects in the default config search on macOS.
  • Codex: scans both $CODEX_HOME/sessions (or ~/.codex/sessions) and ~/Library/Developer/Xcode/CodingAssistant/codex/sessions on macOS; availability checks cover both and files are read in stable order.
