Subject: [PATCH] fix(web): fix Code/Issues active state in header nav
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

the NavLink active detection couldn't distinguish code vs issues
routes because they share the /$repo prefix

replace NavLink with plain Links that determine active state from
the matched route IDs — checking for _code or _issues layout routes
in the active matches via useRouterState

remove unused NavLink component from button-link.tsx
