Redesign `partio status` with styled session cards

[jcleira]

Description

Redesign the partio status command output to display a clear, human-friendly summary of active and recent sessions using styled terminal output. Each session should be shown as a card with: agent name, session state (ACTIVE/IDLE/ENDED), duration, files modified count, and last activity time. Use ANSI colors/styles for quick visual scanning.

Source

• Origin: Update status tui entireio/cli#448 (changelog 0.4.6)
• Detected from: entireio-cli

Target Repos

• cli

Acceptance Criteria

• partio status displays each session as a distinct card with agent, state, duration, file count, and last activity
• ACTIVE sessions are visually highlighted (e.g., green or bold)
• ENDED/stale sessions are visually de-emphasized
• Output degrades gracefully when NO_COLOR is set or stdout is not a TTY (plain text, no ANSI codes)
• Command completes in under 200ms for repos with up to 50 sessions

Context Hints

• cli/cmd/
• cli/internal/session/
