[FEATURE] /context should use dismissable dialog overlay like /usage

Problem Statement

The /context command dumps its entire output inline into the terminal scrollback. For users with many memory files, skills, or MCP tools, this can be 30+ lines that permanently clutter the terminal window.

By contrast, /usage opens a dismissable overlay dialog — you view the info, press Escape, and your terminal is clean again. The /context command shows similar at-a-glance diagnostic info but doesn't get the same treatment.

The result: I avoid running /context because it blows out my scrollback every time. That's the opposite of what a quick status check should feel like.

Proposed Solution

Render /context output in the same dismissable overlay/dialog UI that /usage already uses. The user views context breakdown, presses Escape, and the terminal returns to its previous state with a one-line "Status dialog dismissed" confirmation — exactly like /usage behaves today.

No new flags or options needed. Just parity between the two commands' display behavior.
