Session table columns overflow on terminals narrower than 84 columns

[rajfirke]

Problem

defaultColumns() in internal/panel/sessions.go defines 8 columns with fixed widths summing to at least 84 characters (69 fixed + min 15 for Project). On terminals narrower than ~84 columns, the rightmost columns (Cost, Context, Tool/min) are invisible or wrapped.

Suggested Fix

Options:

1. Responsive columns: hide low-priority columns (Tool/min, Iters) when width < 80, hide Context when < 60
2. Proportional widths: calculate all column widths as fractions of total width
3. Horizontal scroll: enable table horizontal scrolling (if bubbles supports it)

Option 1 is simplest and matches how htop handles narrow terminals.
