v2.9.0: Per-Project Isolation

Per-Project Isolation

Locked Mode

• /api/projects\ returns \locked: true/false\ based on \CORTEX_SINGLE_PROJECT\
• \POST /api/projects/switch\ returns 403 with helpful message when locked

Dashboard UI

• Projects tab: amber 'Isolated' banner when locked, 'Start new instance' hint
• TopBar: amber 'isolated' lock badge visible when locked
• Project cards: both API and MCP ports shown (activity + network icons)
• Agent badges: running agent count with port shown on active project cards

Bug Fixes

• \�in/cortex.js: SIGTERM handler for clean agent file cleanup
• Server: \listAgents\ imported, \scanProjects\ includes agent list per project
• \useProjectData\ hook: exposes \isolated\ and \project_agents\ fields
