Bug] autocli generate --ai includes natural language commentary inside the generated YAML file

[nanpuhaha]

Description

The --ai generation logic in autocli 0.3.8 incorrectly includes the AI's thought process and conversational text at the beginning of the generated .yaml file. This results in a Failed to parse YAML error because the file is no longer a valid YAML document.

Environment

• autocli version: 0.3.8
• OS: macOS
• Command: autocli generate https://news.hada.io --goal hada --ai

Actual Behavior

The generated file ~/.autocli/adapters/hada/hada.yaml contains the following non-YAML text at the top:

"Looking at the captured data, I can see this is GeekNews (news.hada.io) — a Korean tech/developer news aggregator..."
This causes the parser to fail with:
error=[adapter] Failed to parse YAML: mapping values are not allowed in this context at line 2 column 11

Expected Behavior

The generated YAML file should only contain the valid YAML structure (starting from site: hada or relevant metadata keys) without any conversational commentary from the AI.

Evidence (File Content Snippet)

Looking at the captured data, I can see this is **GeekNews (news.hada.io)** — a Korean tech/developer news aggregator similar to Hacker News. The data is entirely in the HTML (server-rendered), with no API endpoint. The page lists ranked topics with titles, authors, points, and comment links.
Looking at the captured data, I can see this is GeekNews (news.hada.io) ...
meta_title: "GeekNews - 개발/기술/스타트업 뉴스 서비스"
meta_description: "..."
meta_keywords: "..."

Since this is a pure HTML page with no XHR/fetch API, I'll use DOM scraping via `evaluate`.

```yaml
site: hada
name: hada
