Add a new tabpanel extension that provides airline-styled formatting for Vim's vertical tab panel feature. Uses airline tabline highlight groups (TabPanelFill, TabPanelSel, TabPanel) and refreshes them on theme changes. Requires a Vim version with 'tabpanel' support. Extension implemented using Vim9Script so not Neovim compatible fixes: #2724 closes: #2746 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
