hypr: reassert joplin workspace on window open

Joplin (Wayland-native Electron) reasserts its own window right after it
maps, escaping the map-time `silent` workspace rule, so it opened on the
focused workspace instead of its app-home (ws 4 / HDMI-A-2).

Add a data-driven `reassert` placement flag: rules.lua emits a window.open
handler that re-applies the assignment by address (follow = false, silent)
for flagged apps. Only Joplin opts in; the static rule stays as a fallback
and the other app-homes are untouched. Document the flag in CLAUDE.md and
AGENTS.md.
