docs: correct presence tracking data based on per-client research
- Cinny upstream: ✗ → ~ (manual AFK only, auto-detection PR unmerged)
- Commet: basic → partial (inactivity monitor shipped Oct 2025, PR #475)
- Element Web/Desktop: 'no idle detection' → partial; 3-min idle timer
shipped Nov 2023 (matrix-react-sdk PR #11824), but no tab detection,
no offline-on-close, no user hide toggle
- FluffyChat, Element X, Nheko: basic confirmed, no change
Sources: matrix-react-sdk PR #11824, Commet PR #475, Cinny issue #2395
