Present Open updater as the existing confirm-style button on its own toast row. Opening the Self Update modal now dismisses the persistent notification so users do not need to close it separately.\n\nKeep external update-instruction links unchanged and extend the persistent-toast regression coverage.
Make plugin frontend-reload and Agent Zero update notifications persistent until the user dismisses or acts on them. Reuse the existing zero-duration toast contract without changing ordinary notification timeouts.\n\nDocument the behavior and extend the persistent-toast regression coverage.
Add comprehensive file-level DOX documentation across the repo and update directory AGENTS.md indexes. Many new `*.py.dox.md` files were added under api, helpers, tools, plugins, extensions, webui, and other dirs to document endpoint purpose, ownership, runtime contracts, work guidance, and verification. Several AGENTS.md files were created or updated (agents profiles, api, docker, extensions, helpers, plugins, skills, webui components, etc.) to list child DOX files and clarify documentation/work guidance. Also add example and bundled profile DOX files (agent0, default, developer, hacker, researcher) and minor updates to helpers/dirty_json.py and its tests. These changes improve on-disk documentation coverage and establish the convention that each direct runtime file should have a matching `*.dox.md` describing its contracts and verification steps.
