feat(tui): expand and prioritize footer rotating tips

No issue — the problem is explained below.

Problem

The footer's rotating tips only covered 6 items, so many features users should know about were never surfaced — recent slash commands (/tasks, /auto, /compact, /init, /plugins, /theme), shortcuts (ctrl+s steer, ctrl+o expand tool output, shift+enter newline), the natural-language scheduled-tasks capability, and the superpowers plugin.

What changed

• Expanded the rotating tips from 6 to 16, covering recent commands, shortcuts, and capabilities.
• Long/important tips (the superpowers plugin via /plugins, scheduled tasks) now take their own line; short tips still pair up two at a time when width allows.
• Added a per-tip priority weight (smooth weighted round-robin) so newer/important tips rotate more often while staying evenly spread.
• Changed the rotation interval to 10s.
• Added unit tests for the weighting.

Scope is limited to the footer component plus its unit test — no config-file or schema changes.
