v0.3.0 — Project-scoped polling & single-project view

What's New

Project-scoped polling

• Poll data is now filtered by the selected project — sessions, messages, and plan progress are all scoped
• Project auto-selection on startup: URL param → server --project flag → first project in list
• --project <path> CLI flag threads through as default project via health endpoint

Single-project view

• Removed "All Projects" view — dashboard always shows one project at a time
• Simplified project dropdown (no more "All Projects" option at bottom)
• Removed per-session project badges (unnecessary in single-project mode)

Bug fixes (from code review)

• Fixed cross-project response race: Hooks now use combined sessionId+projectId scope key to detect stale responses during rapid project switching
• Fixed test workflow regression: Removed bunfig.toml root that broke integration test discovery
• Eliminated duplicate listAllSessions() call: resolveProjectDirectory now accepts pre-loaded sessions
• Added project-scoped poll cache: Cache keyed by projectId instead of global-only — scoped requests now benefit from caching and deduplication
• Session cleared on project switch: selectedSessionId resets when changing projects
• Auto-selected project validated: Stale ?project= URL params no longer lock users into empty scope
• Graceful directory-missing degradation: Shows sessions even when project directory is gone, only plan data is null

Tests

• Added hook tests for projectId URL construction, scope key reset, and stale response rejection
• Added server tests for scoped cache 304 responses and cache isolation across projects
• Added SidebarPlanProgress, health route, and project resolver test suites
