feat: ungate sidebar agent + raise timeout to 5 minutes (v0.12.0)

Browse Source 
Sidebar chat is now always available in headed mode — no --chat flag needed.
Agent tasks get 5 minutes instead of 2, enabling multi-page workflows like
navigating directories and filling forms across pages.

Changes:
- cli.ts: remove --chat flag, always set BROWSE_SIDEBAR_CHAT=1, always spawn agent
- server.ts: remove chatEnabled gate (403 response), raise AGENT_TIMEOUT_MS to 300s
- sidebar-agent.ts: raise child process timeout from 120s to 300s
