@NishchayRajput Thank you for taking this on. The mechanical migration looks consistent, and moving alt screen into the view state is exactly how v2 intends it.

Testing against the demo Harbor instance surfaced two regressions, both in shared base views (so two fixes cover all call sites). Both have the same root cause: v2 clips to the terminal cell buffer, while v1 flushed the final frame regardless of size.

1. tablegrid renders blank (robot create permission grid): tablegrid.New never sets table.WithWidth(...). In bubbles v2 the table's viewport defaults to width 0 and renders "". Fix: compute the width from the columns and pass table.WithWidth(tableWidth), same as tablelist/model.go already does.

2. tablelist cuts tall tables and leaks escape codes (project list etc., 44 files): these views quit in Init(), so v2 clips the frame to terminal height, and the startup terminal queries (DECRQM) land in the shell as garbage (2026;2$y...). Fix: skip tea.NewProgram for these print-once views and use the pattern this PR already applies in info.go:

   fmt.Println(m.View().Content)

For verification, one command per base class covers everything: project list, artifact list, robot create, login. selection already looks correct.

Follow-up material, fine to defer: pkg/views/base/multiselect is now dead code, and tablegrid could scroll instead of clip via WindowSizeMsg.
