Add markdown export

[hellovietduc]

Resolves #38

Markdown output is great for certain workflows. This PR adds a --markdown flag to the local, json, and web commands.

• --open with --markdown opens the file in $EDITOR/$VISUAL (falls back to click.launch())
• --gist with --markdown uploads the .md file to GitHub Gist (GitHub renders it natively, so no preview URL needed)

(eval):1: command not found: uv

Assistant

That's the issue — uv isn't installed. This project uses uv as its package manager. To get set up:

1. Install uv:

curl -LsSf https://astral.sh/uv/install.sh | sh

Or via Homebrew:

brew install uv

2. Sync dependencies:

uv sync

This will create a .venv, install Python (if needed), and install all dependencies including dev ones.

3. Verify it works:

uv run pytest
uv run claude-code-transcripts --help

Would you like me to run the install for you?

Perfect! Here's a comprehensive guide to installing uv using asdf:

## Summary

Yes, there is an official asdf plugin for uv! The [asdf-community/asdf-uv](https://github.com/asdf-community/asdf-uv) plugin is maintained and allows you to install and manage uv versions through asdf, just like you would with other development tools.

## Installation Steps

1. **Add the asdf-uv plugin:**
   ```bash
   asdf plugin add uv
   ```
   
   Or explicitly specify the repository:
   ```bash
   asdf plugin add uv https://github.com/asdf-community/asdf-uv.git
   ```

2. **List available versions:**
   ```bash
   asdf list all uv
   ```

3. **Install a specific version:**
   ```bash
   asdf install uv latest
   ```
   
   Or install a specific version number:
   ```bash
   asdf install uv 0.4.0
   ```

4. **Set the version globally:**
   ```bash
   asdf global uv latest
   ```
   
   Or for a local project only:
   ```bash
   asdf local uv latest
   ```

5. **Verify installation:**
   ```bash
   uv --version
   ```

## System Requirements

The asdf-uv plugin requires:
- bash
- curl
- tar
- POSIX utilities

These are standard on most Unix-like systems including macOS and Linux.

## Benefits

Using asdf to manage uv allows you to:
- Manage uv versions alongside other development tools
- Specify uv as part of your project's tool requirements
- Switch between different uv versions easily
- Use per-project version specifications via `.tool-versions` file

Yes! There's an official asdf plugin for it:

asdf plugin add uv
asdf install uv latest
asdf global uv latest

Then verify with uv --version, and you should be good to run uv sync in the project.
