feat: wholesale pipeline visualization

[jonahsalama]

Summary

• Rewire Pixel Agents extension to visualize 3 wholesale real estate pipeline agents (Lead Scout, Outreach Engine, Deal Closer)
• Replace Claude Code JSONL tracking with 4 data sources: SQLite polling (wholesale.db), trigger file watching (.triggers/), process detection (pgrep), and log file tailing
• Add StatusOverlay showing live pipeline metrics (leads, outreach stats, deals, send window status)
• Remove dynamic agent add/remove — 3 fixed agents with predefined palettes

Architecture

New backend modules:

• wholesaleDataPoller.ts — Polls wholesale.db via better-sqlite3, computes send window (Central Time)
• triggerWatcher.ts — Watches .triggers/ directory for inter-agent signals
• processDetector.ts — Detects running Python agent processes via pgrep
• logTailer.ts — Tails agent log files with byte-offset tracking
• agentStateMapper.ts — Combines all sources into WholesaleStateSnapshot

Removed (Claude-specific):

• agentManager.ts, fileWatcher.ts, transcriptParser.ts, timerManager.ts

Test plan

• Verify extension activates without errors in Extension Dev Host
• Confirm 3 agents appear in pixel art office with correct names
• Test with wholesale.db present — StatusOverlay shows pipeline metrics
• Test without wholesale.db — graceful fallback to empty snapshot
• Verify process detection correctly shows running/absent states
• Test trigger file creation causes character animation changes
• Verify send window logic matches Python timing_engine.py behavior
