Framework detection matched a dependency against a framework's packageKeys
with unbounded substring containment (dep.includes(key)), so any dependency
whose name merely contained a key was misclassified: `preact` and even
`reactive` were both detected as `react`.
Match only when the dependency equals the key, or the key is a prefix
immediately followed by a delimiter (/ . _ -). This still matches every real
case (react-dom, @remix-run/node, spring-boot-starter, org.springframework.boot,
github.com/labstack/echo/v4, phoenix_live_view) while excluding preact/reactive
(and incidentally nextra). Adds regression tests.
