Implement SDK pre-submission verification command

[El-swaggerito]

Description

Difficulty: Expert

Type: CI

Summary

Add one local command that contributors can run before submitting SDK PRs.

Current Behaviour

Contributors may submit work without running lint, typecheck, tests, or coverage locally.

Expected Behaviour

The SDK should provide a single verification command that mirrors expected CI checks.

Suggested Implementation

Add package script, documentation, failure guidance, and README reference.

Files or Areas Likely Affected

• package.json
• docs/
• README.md
• tests/

Acceptance Criteria

• Verification command is added.
• Command runs relevant local checks.
• Documentation explains usage.
• Failure guidance is included.
• README links to command.
• Command is suitable for contributors before PR submission.

Additional Notes

This helps reduce failing CI checks.
