v0.3.0 Custom components

What's Changed

• Feat custom components by @VeiaG in #9

Custom components

Full custom component support across the entire sidebar:

Slot	Config key	Description
Nav item	customComponents.NavItem	Replace individual collection/global links
Nav group	customComponents.NavGroup	Replace group headers with expand/collapse
Tab button	customComponents.TabButton	Replace tab/link buttons in the icon bar
Tab icon	iconComponent on tab/link	Override the icon only, keep default button
Nav content area	customComponents.NavContent	Replace the entire scrollable nav panel
Tabs bar slot	type: 'custom' tab item	Inject arbitrary elements between tabs

All components are server-rendered and receive serverProps (payload, i18n, user, etc.).

Access control

Added access functions to tabs, links, and custom nav items. Evaluated server-side with full PayloadRequest — fails closed (denies access) when req is unavailable.

{
  id: 'admin',
  type: 'tab',
  icon: 'Settings',
  label: 'Admin',
  access: ({ req }) => req.user?.role === 'admin',
}

Custom tabs bar slots (type: 'custom')

New tab bar item type for injecting arbitrary server-rendered components (separators, custom buttons, etc.) between tabs.

{ id: 'sep', type: 'custom', component: './components/TabSeparator' }

Tooltips on tab buttons

Default tab buttons and links now show a tooltip with the tab label on hover/focus, positioned to the right of the sidebar.
