docs: update to v1.0.3 and remove redundant Examples section

[clouatre]

Simplifies README by removing redundant examples.

Changes:

• Update version table to v1.0.3
• Update recommended usage example to v1.0.3
• Remove entire Examples section (Basic Usage, Specify Version, Use Outputs, Complete Workflow Example)

Rationale:

• Quick Start already shows a complete working example
• Examples section was redundant and confusing
• Complete Workflow Example had same issue as previous PR - didn't post to PR
• One clear example is better than multiple confusing ones
