docs(tasks): migrate active task queue into Peek; tasks.md becomes a pointer
The 16 active engineering todos in docs/tasks.md migrated to Peek items
(via mcp__peek__create_item) with markdown bodies and namespaced peek:*
machine tags (peek:todo plus domain peek:desktop / peek:mobile / peek:tauri
/ peek:atproto / peek:extensions plus type peek:bug / peek:feature /
peek:test-coverage / peek:docs / peek:design / peek:security / peek:deferred
/ peek:tile-arch).
Also retagged ~245 existing #peek items: bare todo / desktop / mobile /
daily-use tags replaced with their peek:* equivalents (~750 untag+tag
mutations). The dail-use typo (1 item) was normalized to peek:daily-use.
Bare #peek left untouched as the project membership marker, in advance
of project workspaces.
The active queue now lives in Peek; query peek:todo (intersect with
narrower peek:* tags as needed). docs/tasks.md retained as a one-page
pointer.
