feat: add per-tab isolation for multi-agent safety
Replace singleton dialog, pageInfoDirty, networkBuffer, and consoleBuffer
with per-tab TabSession objects stored in a Map<string, TabSession>.
- Add TabSession type (sessionId, targetId, dialog, pageInfoDirty,
networkBuffer, consoleBuffer) and tabs/sessionIdToTargetId Maps
- Add ev.sessionId filter guard in consumeEvents to prevent cross-tab
event contamination
- Rework switchTo to create/reuse TabSession without clearing buffers,
updating sessionId on re-attach
- Route all CDP events (dialog, network, console) through resolveTab
to the correct TabSession
- takeDialog/drainPageInfoInvalidations/drainNetworkBuffer/
drainConsoleBuffer read from current TabSession
- Target.targetDestroyed prunes dead TabSession entries
- attachFirstPage creates initial TabSession and prunes dead entries
- Per-tab pageCaches Map in client.ts replaces pageCache singleton
- listTabs reconciliation prunes dead pageCaches entries
- console-buffer.ts clear() resets nextSeq to 1 (per-tab seq space)
- Multi-agent warning in prompt.ts Parallel Execution section

Per-tab data (console buffers, network traces, dialogs, page info cache) is isolated — switching tabs does not destroy another agent's collected data. Call \`browser_current_tab\` before mutation tools to confirm you're on the expected tab.
