## What is the current behavior?
When using ion-tabs with routes that share a common prefix (e.g.,
`/home`, `/home2`, `/home3`), navigating to `/home2` incorrectly
highlights the `/home` tab. This occurs because the tab matching logic
uses `pathname.startsWith(href)`, which causes `/home2` to match `/home`
since `/home2` starts with `/home`.
## What is the new behavior?
Tab selection now uses path segment matching instead of simple prefix
matching. A tab's href will only match if the pathname is an exact match
OR starts with the href followed by a / (for nested routes). This
ensures /home2 no longer incorrectly matches /home, while still allowing
/home/details to correctly match the /home tab.
