Implement core workers, Healdec auto-healing engine, and Operator Dashboard UI

[Copilot]

Implements foundational components for repository health monitoring platform: IndexWorker, IdentityWorker, ScoreWorker (completing from 50-70% to 100%), Healdec retry/restart strategies (completing from 40-80% to 100%), and Operator Dashboard UI (completing from 40% to 100%).

Backend: Workers & Auto-Healing

Worker Implementations

• IndexWorker: Repository discovery from GitHub orgs with visibility filtering
• IdentityWorker: Git commit identity extraction with deduplication and merging
• ScoreWorker: 5-component health scoring (documentation, testing, security, maintenance, community) with 0-100 scale

// Health score computation with weighted breakdown
const score = Math.round(
  documentation * 0.20 +
  testing * 0.25 +
  security * 0.25 +
  maintenance * 0.20 +
  community * 0.10
);

• BaseWorker: Abstract class providing lifecycle management, timeout handling, job execution

Healdec Strategies

• RetryStrategy: Exponential backoff with jitter for transient failures: baseDelay * 2^attempt ± 20%
• RestartStrategy: Worker crash recovery with graceful shutdown → force kill → restart → job reassignment
• HealdecEngine: Failure classification (transient, crash, data_error, partial_success, critical) with pattern-based detection

Frontend: Operator Dashboard & Components

Operator Dashboard

Real-time worker monitoring with system vitals, job queue stats, and 12-worker status grid.

Repository Dashboard

Repository cards with health scores, metrics, and SmartBrainTerminal log viewer.

Components

• Layout System: TopNav + responsive container
• RepoCard: Health score badges with color-coded states (Aqua: 80-100, Yellow: 60-79, Coral: 0-59)
• VitalsModal: Health dashboard with 5-component breakdown and progress bars
• SmartBrainTerminal: Terminal-styled log viewer with timestamp, worker tags, severity coloring

Infrastructure

Shared Types & Utilities

• Types: Repository, Identity, Job, Worker, Event, HealingAttempt
• Logger with context, custom error classes, retry helpers with exponential backoff

Monorepo Setup

• pnpm workspaces: shared, workers, healdec, ui
• TypeScript strict mode, ESM modules
• Vite 7 for UI (64.25 kB gzipped), tsup for packages

Design System

Aura FX Neo-Glow palette: Violet (#A78BFA), Aqua (#4FD1C5), Coral (#F87171), Cyber Yellow (#FACC15) on GitHub Dark base.

Fixes

• Infinite loop in SmartBrainTerminal useEffect (moved mock data to lazy initializer)
• Initial route handling for /operator path (check pathname on mount)
