feat(phase2): add message queue system for offline projects

Phase 2 Complete: Message queuing for offline/inactive projects

Queue Storage:
- File-based queue in ~/.innervoice/queues/
- Separate JSON file per project
- Persistent storage survives restarts
- Auto-cleanup of old delivered tasks (7 days)

Queue Manager (queue-manager.ts):
- enqueueTask() - Add task to project queue
- getPendingTasks() - Get undelivered tasks
- markTaskDelivered() - Mark task as complete
- getQueueSummary() - Get overview of all queues
- cleanupOldTasks() - Remove old delivered tasks

API Endpoints:
- POST /queue/add - Queue message for project
- GET /queue/:projectName - Get pending tasks
- POST /queue/:projectName/mark-delivered - Mark delivered
- GET /queue/summary - Get all project summaries

Telegram Bot Features:
- /queue command - Show all queued messages
- Project-targeted messages: "ProjectName: message"
- Auto-detect if project is online or offline
- Queue for offline, deliver immediately if online

MCP Tool:
- telegram_check_queue - Check for queued messages on startup
- Shows pending messages with timestamps
- Perfect for checking what happened while offline

Usage Scenarios:

1. Send to offline project:
   You: "ESO-MCP: Continue with roadmap"
   Bot: "📥 Message queued for ESO-MCP (offline)"

2. Open Claude in ESO-MCP:
   Claude auto-checks queue on startup
   Shows: "📬 You have 1 queued message: Continue with roadmap"

3. Check queue status:
   You: "/queue"
   Bot: Shows all projects with pending messages

This solves the "no one listening" problem - messages are stored
and delivered when Claude opens in that project.

Next: Phase 3 (remote Claude spawner)

+# Phase 1 Testing Guide
+
+## What Was Built
+
+✅ Multi-project session tracking with project context display
+
+### Features
+- Auto-generate unique session IDs for each Claude instance
+- Track project name and path from working directory
+- Show project context in all Telegram messages: `📁 ProjectName [#shortId]`
+- `/sessions` command to list all active Claude instances
+- Auto-expire inactive sessions after 30 minutes
+
+## How to Test
+
+### 1. Restart Claude Code
+**Important:** You need to restart Claude Code to load the new MCP server code.
+
+```bash
+# Exit your current Claude Code sessions
+# Then restart in your project
+cd /path/to/your/project
+claude
+```
+
+### 2. Test Project Context
+Send a notification and you should see the project name:
+
+```
+📁 ESO-MCP [#1a2b3c4]
+ℹ️ Your message here
+```
+
+### 3. Test Multi-Project Sessions
+1. Open Claude in **ESO-MCP** project
+2. Open another terminal and start Claude in **innervoice** project
+3. In Telegram, type `/sessions`
+4. You should see both projects listed:
+
+```
+Active Claude Sessions (2)
+
+1. 🟢 ESO-MCP [#1a2b3c4]
+   Last active: 0m ago
+
+2. 🟢 innervoice [#5d6e7f8]
+   Last active: 2m ago
+```
+
+### 4. Test Session Auto-Expire
+Wait 30 minutes of inactivity, then run `/sessions` again.
+Inactive sessions should be removed automatically.
+
+## Known Issues
+
+- You must restart Claude Code for changes to take effect
+- Old MCP server processes won't pick up new code automatically
+
+## Next: Phase 2

+Message queue system for offline/inactive projects coming next!
