…em-wide scaling - Add ResourceProfileService with hysteresis-based profile transitions (Performance/Balanced/Efficiency) - Add shared ResourceProfile types and per-profile configuration constants - Add set-resource-profile PtyHostRequest type and pty-host handler for ProcessTreeCache adjustment - Add update-monitor-config WorkspaceHostRequest type and handler for live polling interval changes - Add setPollInterval method to ProcessTreeCache for runtime interval adjustment - Add setMemoryPressureThresholdMs setter to HibernationService for profile-based threshold injection - Add setResourceProfile method to PtyClient and updateMonitorConfig method to WorkspaceClient - Convert TerminalWebGLManager.MAX_CONTEXTS from static readonly to getter/setter pattern - Add RESOURCE_PROFILE_CHANGED IPC channel with preload bridge and ElectronAPI type - Add useResourceProfile hook wired into App component for renderer-side WebGL budget adjustment - Wire ResourceProfileService lifecycle into windowServices.ts with lazy dep injection - Add comprehensive test suite (11 tests) covering hysteresis, warmup, oscillation prevention, and null deps
- Fix worktree count signal to use actual worktree count via WorkspaceClient.getAllStatesAsync instead of project count - Move disposed check before state mutation in applyProfile to prevent stale state on post-disposal calls - Add lower-bound validation (Math.max(1, n)) to TerminalWebGLManager.setMaxContexts - Remove getWorktreeCount dep in favor of cached count with async refresh on each eval tick
- Add RESOURCE_PROFILE_CHANGED to inlined CHANNELS in preload.cts - Replace any types with ResourceProfilePayload in preload bridge - Remove unused logWarn import from ResourceProfileService - Fix powerMonitor.isOnBatteryPower to be called as function - Add ResourceProfile type assertion in pty-host message handler
…k types - Use typed Mock interfaces for mock deps instead of any casts - Use vi.Mock type for module-level mock references - Use as unknown as Type pattern for mock-to-interface casts

Summary
ResourceProfileService— a central coordinator in the main process that monitors memory pressure, event loop lag, battery state, and worktree count, then selects one of three profiles: Performance, Balanced, or Efficiency.Resolves #4324
Changes
electron/services/ResourceProfileService.ts— new service: profile evaluation, transition logic, hysteresis timers, IPC broadcastshared/types/resourceProfile.ts—ResourceProfileenum,ResourceProfileConfigtype with all tunable parameterselectron/window/windowServices.ts— initializes and wiresResourceProfileServiceinto the main process lifecycleelectron/pty-host.ts/electron/workspace-host.ts— subscribe to profile updates and propagate config toResourceGovernorandWorkspaceServiceelectron/services/HibernationService.ts,ProcessTreeCache.ts— accept dynamic config overrides from the active profilesrc/hooks/useResourceProfile.ts— renderer hook for consuming the current profilesrc/services/terminal/TerminalWebGLManager.ts— respects WebGL context budget from active profileelectron/services/__tests__/ResourceProfileService.test.ts— 294-line unit test suite covering profile evaluation, hysteresis, and IPC dispatchTesting
