// The Mac's own apps as tools, like Grok Bot's device tools (local-exec-daemon):
//   ios_read_reminders / ios_write_reminders, mobile_read_calendar / mobile_write_calendar,
//   mobile_read_contacts, mac_read_notes / mac_write_notes, mac_read_mail / mac_draft_mail /
//   mac_send_mail / mac_mail_accounts, and sending an iMessage.
// Rules taken from the original:
// - a note or an email is read up to 20,000 characters (zlt=2e4);
// - contacts are fetched 50 at a time (Dlt=50);
// - device calls time out after 30 s (g4r=3e4);
// - writing (reminders, calendar, notes, mail drafts) needs consent; sending mail is only ever
//   approved one message at a time (recordLocalToolApproval refuses a standing grant for it);
// - mac_write_notes appends when given id + currentTitle, else creates (needs a title);
//   mac_draft_mail needs to (or replyToId) and a body.
// The original runs them through its signed helper; here they go through osascript (JXA), so
// macOS asks once per app under 「系統設定 → 隱私權與安全性 → 自動化」.
