Initial commit: Ajarbot with optimizations

Features:
- Multi-platform bot (Slack, Telegram)
- Memory system with SQLite FTS
- Tool use capabilities (file ops, commands)
- Scheduled tasks system
- Dynamic model switching (/sonnet, /haiku)
- Prompt caching for cost optimization

Optimizations:
- Default to Haiku 4.5 (12x cheaper)
- Reduced context: 3 messages, 2 memory results
- Optimized SOUL.md (48% smaller)
- Automatic caching when using Sonnet (90% savings)

+# Quick Start
+
+## Setup (30 seconds)
+```bash
+pip install anthropic requests watchdog
+export ANTHROPIC_API_KEY="sk-ant-..."  # Your Claude API key
+export GLM_API_KEY="..."                # Optional: z.ai GLM key
+```
+
+## Usage
+
+### Basic Agent
+```python
+from agent import Agent
+
+# Initialize with Claude
+agent = Agent(provider="claude")
+
+# Chat (auto-loads SOUL + user context + relevant memory)
+response = agent.chat("What should I work on?", username="alice")
+
+# Switch to GLM
+agent.switch_model("glm")
+response = agent.chat("Explain SQLite FTS5")
+```
+
+### Memory Operations
+```python
+# Update personality
+agent.memory.update_soul("## New trait\n- Be concise", append=True)
+
+# User preferences
+agent.memory.update_user("alice", "## Preference\n- Likes Python")
+
+# Write memory
+agent.memory.write_memory("Completed task X", daily=True)
+
+# Search
+results = agent.memory.search("python")
+```
+
+### Task Tracking
+```python
+# Add task
+task_id = agent.memory.add_task(
+    "Implement API endpoint",
+    "Details: REST API for user auth"
+)
+
+# Update
+agent.memory.update_task(task_id, status="in_progress")
+
+# Get tasks
+pending = agent.memory.get_tasks(status="pending")
+all_tasks = agent.memory.get_tasks()
+```
+
+## Files Created
+- `llm_interface.py` - Claude/GLM integration
+- `agent.py` - Main agent class
+- `memory_workspace/MEMORY.md` - Instructions for future sessions
+- Task system added to memory_system.py
+
+## Context Retrieval
+Agent automatically loads:
+1. SOUL.md (personality)
+2. users/{username}.md (user prefs)
+3. Search results (top 3 relevant chunks)
+4. Recent conversation (last 5 messages)
+
+All indexed in SQLite for fast retrieval.
