docs: align agent example format with official Claude Code documentation

Update example blocks across agent development documentation and all 3 agents
to use the official Claude Code single-assistant-line format with commentary
positioned after the assistant invocation line.

Key changes:
- triggering-examples.md: Updated template and all example types
- agent-creator.md: Updated documented template format
- plugin-validator.md: Converted 3 examples to single-line format
- skill-reviewer.md: Converted 1 example to single-line format

The official format uses:
- Single assistant line (invocation only)
- Commentary positioned after the invocation

Fixes #117
