Custom statusLine is hidden when in plan or bypassPermissions mode

What

When I Shift+Tab into plan or bypassPermissions mode, the mode banner (blue "plan mode on" / red "bypass permissions on") replaces my custom statusLine output. The statusline stays hidden for the entire time I'm in that mode — not just during the brief permission prompt flash mentioned in the docs.

Why it matters

My statusline shows model, context usage, branch, task ID, and cost — info I want visible all the time, not just in default mode. I regularly cycle bypass → plan → bypass for planning then execution, and I lose the statusline each hop.

Proposal

Render the mode badge alongside the custom statusline rather than replacing it. A compact prefix like [PLAN] <statusline output> or a second line would preserve both signals.

Alternatively, expose permission_mode in the statusLine stdin JSON so user scripts can self-render the badge and keep full control of the line.
