Add nine new feature modules with settings UI

[Josh-wt]

What Changed

This PR introduces nine new feature modules with corresponding backend services, frontend stores, contract definitions, and a unified settings panel:

1. Cost Tracking – Records token usage and costs per turn, manages budgets with alerting
2. Audit Log – Structured activity logging with actor, category, and severity metadata
3. CI/CD Integration – Tracks CI runs and manages feedback policies for automated responses
4. Provider Routing – Multi-provider health tracking and intelligent routing with failover
5. Pipelines – Multi-stage pipeline definition and execution with dependency ordering
6. Workflows – Reusable workflow templates with variable substitution
7. Task Decomposition – Breaks down prompts into hierarchical task trees
8. Project Memory – Knowledge base for storing and searching project insights
9. Presence – Real-time session sharing and participant tracking

Each module includes:

• Backend service layer with Effect/SQL integration
• Frontend Zustand store with RPC client bindings
• Contract schemas for type-safe communication
• Database migrations for persistence
• WebSocket RPC method definitions

A new Features Settings Panel (FeaturesPanels.tsx) provides a tabbed UI to view and manage all nine features in one place, with real-time event streaming and status indicators.

Why

These modules provide essential infrastructure for advanced AI orchestration:

• Cost Tracking enables budget management and cost visibility
• Audit Log ensures compliance and security auditing
• CI/CD Integration automates testing and deployment feedback loops
• Provider Routing optimizes for cost, latency, and capability matching
• Pipelines & Workflows enable complex multi-step AI operations
• Task Decomposition breaks down complex problems systematically
• Project Memory preserves institutional knowledge across sessions
• Presence enables collaborative AI sessions

The unified settings panel consolidates feature management into a single, discoverable location.

UI Changes

Added a new Features tab in Settings that displays nine feature cards with:

• Real-time status indicators (loading, error states)
• Feature-specific metrics and controls (budgets, health status, participant counts, etc.)
• Live event streaming for cost alerts, audit entries, CI status, etc.
• Consistent card-based layout with icon and description for each feature

Checklist

• This PR is small and focused
• I explained what changed and why
• I included UI changes (new Features settings panel with nine feature cards)
• Database migrations included for all persistent features

📝 Walkthrough

Walkthrough

This PR introduces nine new domain service layers (Audit, Cost Tracking, CI Integration, Provider Routing, Pipelines, Workflows, Task Decomposition, Project Memory, and Presence) with SQL persistence, event streaming via PubSub, and WebSocket RPC endpoints. A database migration adds supporting tables for all services, and corresponding contract schemas, stores, and UI panels are provided for web integration.

Changes

Cohort / File(s)	Summary
Audit Logging Service apps/server/src/audit/Services/AuditLogService.ts, packages/contracts/src/auditLog.ts	New audit log service with record, query, and streamEvents capabilities. Persists structured audit entries to audit_log table, supports filtering by project/thread/category/severity/actor and timestamp range, publishes events via PubSub.
Cost Tracking Service apps/server/src/cost/Services/CostTrackingService.ts, packages/contracts/src/costTracking.ts	Cost tracking with usage recording, budget management, and spending summaries. Tracks token costs per entry, maintains per-project/global budgets, publishes cost and alert events when thresholds are crossed.
CI Integration Service apps/server/src/ci/Services/CIIntegrationService.ts, packages/contracts/src/ciIntegration.ts	CI/CD integration service providing run status queries, run recording/updates, rerun triggering, and feedback policy management. Persists runs to ci_runs and policies to ci_feedback_policies.
Provider Router Service apps/server/src/routing/Services/ProviderRouterService.ts, packages/contracts/src/routing.ts	Provider selection and health-tracking service for failover and routing logic. Persists routing rules, tracks provider health in-memory, publishes routing decisions and health-update events.
Pipeline & Workflow Services apps/server/src/pipeline/Services/PipelineService.ts, apps/server/src/workflow/Services/WorkflowService.ts, packages/contracts/src/pipelines.ts, packages/contracts/src/workflows.ts	Pipeline orchestration with topological stage execution and status tracking. Workflow service seeds built-in templates and maps workflow variables to pipeline stages. Both publish execution lifecycle events.
Task Decomposition Service apps/server/src/task/Services/TaskDecompositionService.ts, packages/contracts/src/taskDecomposition.ts	Task tree decomposition and execution service. Parses prompts into hierarchical tasks, tracks task status, publishes node/tree update events.
Project Memory Service apps/server/src/memory/Services/ProjectMemoryService.ts, packages/contracts/src/projectMemory.ts	Project-scoped memory entries with FTS5 search. Supports add/search/forget/list operations with relevance scoring and automatic expiration handling.
Presence Service apps/server/src/presence/Services/PresenceService.ts, packages/contracts/src/presence.ts	Real-time presence tracking per thread with in-memory participant maps. Manages join/leave, cursor updates, session shares persisted to session_shares table, and event streaming.
Database Migration apps/server/src/persistence/Migrations/020_NewFeatureTables.ts, apps/server/src/persistence/Migrations.ts	Single migration adding 15+ tables: cost_entries, cost_budgets, audit_log, ci_runs, ci_feedback_policies, pipeline_definitions, pipeline_executions, workflow_templates, task_trees, memory_entries, memory_fts (FTS5 virtual table with auto-sync triggers), session_shares, routing_rules.
Server Wiring apps/server/src/server.ts, apps/server/src/server.test.ts, apps/server/src/ws.ts	Integrated nine new service layers into RuntimeDependenciesLive. Added WebSocket RPC handlers for all services with request shaping (e.g., random IDs for executions), streaming subscriptions, and error paths. Added mocked implementations in test configuration.
Web Stores apps/web/src/{auditStore,ciStore,costStore,memoryStore,pipelineStore,presenceStore,routingStore,taskStore,workflowStore}.ts	Zustand-based stores for each service domain. Each store maintains entity state, loading/error flags, async query/mutation actions, and optional event subscription handlers that update state in real-time.
Web RPC Client apps/web/src/wsRpcClient.ts, packages/contracts/src/rpc.ts	Extended WsRpcClient with nine new namespaces (cost, audit, ci, routing, pipeline, workflow, task, memory, presence). Added 40+ RPC method definitions to WS_METHODS with full schema validation.
Web UI Components & Routes apps/web/src/components/settings/FeaturesPanels.tsx, apps/web/src/components/settings/SettingsSidebarNav.tsx, apps/web/src/components/chat/ComposerQueuedFollowUpsPanel.tsx, apps/web/src/routes/settings.features.tsx, apps/web/src/routeTree.gen.ts, apps/web/src/appSettings.ts	New settings "Features" panel with nine sub-panels (cost, audit, CI, routing, pipelines, workflows, tasks, memory, presence) displaying domain-specific data, status indicators, and controls. Added follow-up behavior setting ("steer" or "queue") and queued follow-ups UI in ChatView. Updated routing and navigation.
Orchestration Extensions apps/server/src/orchestration/{decider,projector}.ts, apps/server/src/orchestration/Schemas.ts, packages/contracts/src/orchestration.ts	Added thread.branch-from-checkpoint command and event. Decider validates source thread and checkpoint existence, creates branched thread with filtered checkpoint/message/activity data. Projector derives retained turns, copies related data, updates new thread state, and publishes branched event.
