docs: add examples to macro-vs-micro principle demonstrating 100x productivity

## Summary
Update the OSE principle's "Micro vs Macro" section with concrete examples showing the 100x productivity multiplier in action.

## Current State
The principle explains the theory but lacks specific examples of how tmux + git worktrees + Claude Code delivers exponential gains.

## Proposed Addition
Add examples section showing:
- Single developer managing 3-5 parallel implementations
- Real command sequences: `tmux new-window`, `/close-issue 931`, switch panes
- Time comparison: 1 hour sequential vs 10 minutes parallel orchestration
- Concrete scenario: bug fix + feature + documentation update simultaneously

## Why This Matters
Teams need to SEE the 100x claim validated with real workflows, not just mathematical formulas.

Principle: ose
Principle: transparency-in-agent-work

Locate the OSE principle's "Micro vs Macro" section and the transparency-in-agent-work principle in the repository. Read the surrounding documentation first, then add the requested parallel-workflow examples, command sequences, time comparison, and bug-fix/feature/documentation scenario; done means the 100x claim has concrete, understandable demonstrations.
