Add configurable iteration multiplier (--multiplier)

[vavasilva]

Summary

Add a --multiplier flag to allow users to adjust the iteration estimate calculation.

Current Behavior

• Iterations are calculated as tasks × 3 (fixed multiplier)

Proposed Behavior

• Allow --multiplier <n> to customize: tasks × n
• Default remains 3 if not specified

Use Cases

• Simple tasks: --multiplier 2 (faster)
• Complex tasks: --multiplier 5 (more thorough)
• Quick prototypes vs production-ready code

Examples

/ralph-planner:feature "Add login" --multiplier 2
/ralph-planner:migration "Database upgrade" --multiplier 5

Affected Commands

• All template commands (feature, bugfix, refactor, migration, performance)
• plan-loop
• from-file
• from-issue
