v3.0.1

Archify 3.0.1 makes stable update reminders part of normal diagram delivery. `finalize` and standalone `deliver` now include a bounded update result in their receipts and terminal output, and the Skill carries one reminder into its final response when a newer verified release is known. A reminder repeats until the user updates or explicitly asks to snooze it for seven days or ignore that exact release. Checks use the fixed official manifest and cached results; no update installs automatically.

The diagram format, generated HTML/SVG content, validation quality gates, and existing path protections are unchanged. See the [changelog](https://github.com/tt-a1i/archify/blob/v3.0.1/CHANGELOG.md) for the full entry.
