feat: tab ownership — isolate harness tabs from the user's browsing
Track which page targets this harness session opened so the agent can never
attach to, switch to, or close a tab the user opened themselves. New tabs
are spawned in a dedicated Chrome window (newWindow:true on first open,
openerId chaining after) so harness activity stays visually separate.
- new OwnershipRegistry (src/cdp/ownership.ts) tracks owned targetIds and
the harness window seed; mutations notify a single listener that persists
to BrowserState (ownedTargetIds, harnessWindowTargetId)
- attachFirstPage prefers an already-owned live target; otherwise opens a
fresh harness-owned tab in its own window instead of grabbing whatever
page the user is on
- session subscribes Target.setDiscoverTargets and reaps targetDestroyed
events so the registry stays in sync with reality
- listTabs returns owned:boolean per tab and reconciles dead ids
- browser_list_tabs defaults to scope:"owned"; pass scope:"all" to inspect
the user's other tabs (read-only — they cannot be switched to or closed)
- browser_switch_tab refuses non-owned tabs, with a clear remediation hint
- browser_new_tab opens inside the harness window via openerId, falling
back to a fresh window when the seed has been closed
- new browser_close_tab tool — owned tabs only, supports unique hex prefix
