 * Shared Agentic Bridge admin section nav.

 * Expects `$thedotdev_agentic_bridge_shell_active` (string) identifying the current surface:
 * overview | findings | ai-preview | content | artifacts | privacy | safety | cloud | settings | setup
 *
 * Optional `$thedotdev_agentic_bridge_shell_nav_mode`:
 * - `full` — all real section tabs inline (legacy / explicit)
 * - `progressive` — ≤3 primary tabs + accessible More menu (first-run and post-scan hierarchy)
 *
 * Optional `$thedotdev_agentic_bridge_shell_primary_keys` (list of tab keys) when mode is progressive.
 * Defaults: overview, settings, setup (first-run). Post-scan callers pass overview, findings, ai-preview.
