* fix: use smaller tab padding for 10-tab layout

* style: add thin border separators between tab links

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* style: redesign tabs with folder-tab appearance

Active tab connects to page content with matching background
and rounded top corners. Inactive tabs stay in the bar.

* revert: go back to simple tab style with accent underline
