feat: forward optional per-item triggerProps onto Tabs triggers

[tmccoy14]

Summary

Adds an optional triggerProps field to each Tabs item, forwarded onto that item's TabsTrigger. This lets consumers attach event handlers or attributes to an individual tab — e.g. per-tab hover/focus prefetching (warming a destination's data when the user shows intent toward a specific tab). Previously the only workaround was wrapping the whole tab strip, which can't distinguish which tab is being pointed at.

Changes

• tabs.tsx — added triggerProps?: Omit<ComponentPropsWithoutRef<typeof TabsTrigger>, "value"> to the item shape and spread it onto each trigger.
  • Spread before the library-owned props, so value (selection) and internal styling can't be overridden.
  • className is merged via cn, not clobbered — consumers can add classes without losing the internal ones.
  • Event handlers pass through to Radix's Trigger, which composes them with its own via composeEventHandlers, so tab activation and keyboard navigation are unchanged.
• Removed the leftover data-tour attribute — it was the last reference in the repo, from the retired app tour. If needed again, it now flows through triggerProps like any other attribute.
• tabs.mdx — documented the new field in the TabItem table and added a "Forwarding trigger props" section with a prefetch example.

Notes

• Non-breaking — triggerProps is optional; existing callers are unaffected. Ship as a minor.
• Verified with tsc --noEmit and eslint (both clean).

Testing

No test runner exists in this repo yet, so no automated test was added. Manual coverage to verify: forwarded onPointerEnter/onFocus fire on the correct trigger, forwarded onClick still activates the tab, a custom className is merged with the internal one, and arrow-key navigation still works.

Pull request overview

This PR extends the Tabs component API to allow forwarding per-item props onto individual tab triggers (e.g., for per-tab prefetch handlers), updates the Tabs documentation to describe the new capability, and bumps the UI package version.

Changes:

• Add triggerProps to each Tabs item and spread it onto the corresponding TabsTrigger, merging className safely.
• Document triggerProps usage and update the TabItem props table in the demo MDX docs.
• Bump @eqtylab/equality package version to 2.3.2.
