v1.46.0

The Import Hub shows every way content gets in — including the extension-captured sources

The "Choose a source" grid only showed four tiles, so three real ingestion paths were invisible: X bookmarks and both LinkedIn captures existed through the browser extension but had no way in from the app. The grid now lists all seven sources. The three extension ones open a plain explainer instead of pretending to be forms — what gets captured, the exact page to browse so capture runs, and a direct link where one is guaranteed to land (X Bookmarks and LinkedIn's saved posts; LinkedIn posts keeps instructions only, since the app can't know your profile address).

• Extension tiles carry a "via extension" chip so it's clear before clicking what each one does.
• Nothing about how imports work has changed — this makes the paths that already existed findable.
