feat: Add 4 missing presets (mob-programming, socratic-learning, confession-loop, pdd)

[rubenmarcus]

Current State

Ralph-starter already has excellent preset coverage:

• Development: feature, feature-minimal, tdd-red-green, spec-driven, refactor
• Debugging: debug, incident-response, code-archaeology
• Review: review, pr-review, adversarial-review
• Documentation: docs, documentation-first
• Specialized: api-design, migration-safety, performance-optimization, scientific-method, research, gap-analysis

Missing Presets

1. mob-programming

Description: Simulated mob programming with multiple perspectives

'mob-programming': {
  name: 'mob-programming',
  description: 'Simulated mob programming with rotating roles',
  maxIterations: 40,
  validate: true,
  commit: true,
  promptPrefix: 'Simulate mob programming: rotate between Driver (writes code), Navigator (reviews direction), and Mob (provides input). After each significant change, rotate roles and review.',
}

2. socratic-learning

Description: Learning through dialogue and questioning

'socratic-learning': {
  name: 'socratic-learning',
  description: 'Learn through questioning and exploration',
  maxIterations: 30,
  validate: false,
  commit: false,
  promptPrefix: 'Use the Socratic method: ask probing questions, challenge assumptions, explore edge cases. Document insights and understanding gained.',
}

3. confession-loop

Description: Builder-Confessor-Handler introspective cycle

'confession-loop': {
  name: 'confession-loop',
  description: 'Introspective Builder-Confessor-Handler cycle',
  maxIterations: 35,
  validate: true,
  commit: true,
  promptPrefix: 'Follow the confession loop: 1) Builder creates implementation, 2) Confessor admits weaknesses/concerns, 3) Handler addresses confessions. Iterate until confident.',
}

4. pdd-to-code-assist

Description: Prompt-Driven Development workflow

'pdd-to-code-assist': {
  name: 'pdd-to-code-assist',
  description: 'Prompt-Driven Development flow',
  maxIterations: 30,
  validate: true,
  commit: true,
  promptPrefix: 'Follow PDD: 1) Write detailed prompts describing desired behavior, 2) Generate code from prompts, 3) Validate against prompts, 4) Refine prompts if needed.',
}

Implementation

Add to src/presets/index.ts in a new "Collaborative" category.
