docs: Add personal priority note about hands-off keyboard goal

## Documentation Update
Add a personal reminder to README.md about the goal of optimizing for hands-off keyboard operation.

## Context
As mentioned by the user: "i might want to add to the README.md a reminder of that as a personal priority (a note to myself, note for claude)"

## Proposed Addition
Add a section to README.md that documents:
- Personal goal of hands-off keyboard operation
- Why this matters for focus and higher-level work
- How this relates to autonomous Claude operation
- Connection to the Snowball Method

## Suggested Content
```markdown
## Personal Development Priority: Hands-Off Keyboard

A key personal goal is optimizing for hands-off keyboard operation. This means:
- Claude should run autonomously without constant approval prompts
- Notifications when tasks complete, not constant monitoring
- Permission systems that enable safe autonomous operation
- Focus on issue creation and strategy, not implementation babysitting

This aligns with the Snowball Method - each improvement in autonomy compounds,
freeing more time for high-value creative and strategic work.
```

## Location
Consider adding after the Snowball Method section or in a new "Development Philosophy" section.

Related: #592 (parent task)

Open README.md and locate the Snowball Method section or the surrounding development-philosophy content. Add the requested personal priority note there, covering hands-off keyboard operation, autonomous Claude operation, notifications, permissions, and the Snowball Method connection. Done means the new section is present, readable, and correctly formatted in the README.
