Introduce Shared Error Code Taxonomy Across Contracts

[Baskarayelu]

Description:

Standardize error codes/categories across all contracts so clients can handle failures consistently.

Requirements

• Define top-level categories (AUTH, VALIDATION, STATE, LIMIT, SYSTEM, INTEGRATION, etc.).
• Map each contract’s existing errors/panics into these categories (via docs or numeric ranges).
• Document a client-side decoding strategy.

Acceptance Criteria

• Error taxonomy documented
• Each contract’s errors mapped into taxonomy
• Example client error-handling snippet added to docs
