v0.3.0 — munim-computer-use

Drive a tab the user already has open

The extension could only work in tabs it created. That is the right default — the user keeps browsing while a task runs — but it is the wrong answer when the page is already signed in or mid-flow: a checkout, a draft, a dashboard behind SSO. Re-opening the URL throws that state away.

New tools

• browser_use_tab — adopt a tab the user already has open. Adoption is in place: the tab is not moved into the agent's group, not activated and not reloaded, so a user looking straight at it sees nothing move. Background interaction over the DevTools protocol is what makes this useful at all.
• browser_release_tab — hand the tab back early, detaching the debugger and restoring the favicon.
• browser_list_tabs gains all=true, listing every tab in the browser with its ownership.

An adopted tab stays the user's: cleanup releases it rather than closing it, and browser_close_tab releases it too. Chrome's own pages are refused up front, since the debugger cannot attach to them.

Tool count moves 26 → 28 on both native hosts.
