PIL codebase reader tool

Enable Ava to read PodcastItLater source code for context.

Context

Ava needs to understand PodcastItLater's codebase to provide accurate context when doing customer acquisition - understanding features, pricing, how it works, etc.

Requirements

The existing read_file tool in Omni/Agent/Tools.hs can already read files. This task is about: 1. Adding read_file to Ava's tool list if not present 2. Documenting which PIL files are most relevant for Ava

Key PIL Files for Ava

• Biz/PodcastItLater.md - Main README with features
• Biz/PodcastItLater/DESIGN.md - Architecture overview
• Biz/PodcastItLater/Web.py - Web interface code
• Biz/PodcastItLater/Core.py - Core logic
• Biz/PodcastItLater/Billing.py - Pricing/billing logic

Implementation

1. Check if read_file tool is in Telegram agent's tool list 2. If not, add it to the tools list in Omni/Agent/Telegram.hs 3. Update Ava's system prompt to mention PIL codebase access

System Prompt Addition

Add to telegramSystemPrompt in Omni/Agent/Telegram.hs:

## podcastitlater context

you can read the PodcastItLater codebase to understand the product:
- Biz/PodcastItLater.md - product overview
- Biz/PodcastItLater/DESIGN.md - architecture
- Biz/PodcastItLater/Web.py - web interface
- Biz/PodcastItLater/Billing.py - pricing

use read_file tool to access these when discussing PIL features.

Files to Modify

• Omni/Agent/Telegram.hs (add tool + prompt section)

Verification

• bild Omni/Agent/Telegram.hs
• Manual test: Ask Ava about PIL features, verify it reads files
